51 I'm currently a [[/uw][graduate student]] in the Waterloo Formal Methods group
52 at University of Waterloo. I just finished my degreeā€™s coursework
53 requirements in Fall 2018, and will be focusing on my thesis starting
54 this term, Winter 2019.
55
56 In my spare time, I write [[https://www.gnu.org/philosophy/free-sw.en.html][free software]] (see my [[/projects][projects]] page), and
57 tend to various tasks as a GNU webmaster. I've also been picking up
58 the guitar, after giving up on my longtime dream of being a pianist

136 This is my personal website, previous versions of which I've ran on
137 different domains since 2012. I've previously used Octopress, Jekyll,
138 a [[https://github.com/aminb/blog-old][custom]] static site generator written in Haskell (kudos to [[https://ruudvanasseldonk.com][Ruud van
139 Asseldonk]]), [[https://www.romanzolotarev.com/ssg.html][ssg]] (shout out to [[https://www.romanzolotarev.com][Roman Zolotarev]]), and [[https://orgmode.org/manual/Publishing.html][org-publish]] (see
140 also [[https://ambrevar.xyz/blog-architecture/index.html][A blog in pure Org/Lisp]]); but I've since ported it to [[https://ox-hugo.scripter.co/][ox-hugo]], a
141 "carefully crafted Org exporter back-end for Hugo" (kudos to [[https://scripter.co][Kaushal

143
144 The sources are available at [[https://git.aminb.org/aminb.org]]. On each
145 =git push=, the repository is mirrored from my personal server to my

261 This post summarizes how I install and dual-boot Arch GNU/Linux with
262 Full-Disk Encryption alongside macOS. It is not meant to be a
263 replacement for the [[https://wiki.archlinux.org/index.php/installation_guide][Installation Guide]] or the former [[https://csdietz.github.io/arch-beginner-guide/][Beginner's Guide]].
264 Rather, it mostly serves as a small summary with a few useful notes
265 about the gotchas.
266
267 So, make sure you understand what you type into your terminal. If you
268 don't, checking out the Arch wiki should probably be your first step.
269
270 /Note:/ you will need internet access throughout the installation and
271 the MacBook Air's WiFi doesn't work out of the box on Arch. I
272 recommend using your phone's USB Tethering (if it does support it), or
273 using an Ethernet-USB adapter.
274
275 *** Shrinking the macOS partition
276
277 The first step I take is resizing the HFS+ macOS partition to make
278 room for the new {{{abbr(GNU/Linux)}}} installation. There are plenty
279 of tutorials on how to do this using macOS's Disk Utility, so do that
280 and then come back!
281
282 *** Creating a bootable Arch Installer USB
283
284 There are different ways of creating a bootable Arch USB, all
285 documented on the [[https://wiki.archlinux.org/index.php/USB_flash_installation_media][USB flash installation media]] page on the Arch wiki,
286 but the simplest one is using =dd= if you already have access to
287 another UNIX system.
288
289 {{{span(red,Warning:)}}} make sure you backup the data on your flash
290 drive, as =dd= will irrevocably destroy all data on it.
291
292 Use =lsblk= to find the name (block device) of your USB drive, then
293 run =dd= (as root) as shown below:
294
295 #+begin_src bash
296 dd bs=4M if=/path/to/archlinux.iso of=/dev/sdx status=progress && sync
297 #+end_src
298
299 Replace =/path/to/archlinux.iso= with the path to the Arch image you
300 have downloaded, and =/dev/sdx= with your drive.
301
302 *** Booting up from the USB
303
304 After creating the install USB, reboot your laptop and hold the alt
305 key and boot into the USB.
306
307 When booting is complete and you're presented with the prompt, it's a
308 good time to make sure you're connected to the internet (see the
309 /note/ at the top of this post).
310
311 Use =ping= to verify that you've established a connection:
312
313 #+begin_src bash
314 ping archlinux.org
315 #+end_src
316
317 *** Updating the system clock
318
319 Once you're connected to the internet, make sure the system clock is
320 accurate:
321
322 #+begin_src bash
323 timedatectl set-ntp true # start and enable systemd-timesyncd
324 #+end_src
325
326 You can check the service status using =timedatectl status=.
327
328 *** Partitioning
329 :PROPERTIES:
330 :CUSTOM_ID: partitioning
331 :END:
332
333 I won't dive into partitioning and instead, I'll refer you to the
334 [[https://wiki.archlinux.org/index.php/Partitioning][Partitioning]] page of Arch wiki. Of the available partitioning tools, I
335 personally prefer =cfdisk=.
336
337 *** Setting up LVM & LUKS
338
339 I use a [[https://wiki.archlinux.org/index.php/Dm-crypt/Encrypting_an_entire_system#LVM_on_LUKS][LVM on LUKS]] setup, where I set up LVM on top of the encrypted
340 partition.
341
342 First, let's set up the underlying encrypted partition:
343
344 #+begin_src bash
345 cryptsetup -v --cipher aes-xts-plain64 --key-size 512 --hash sha512 \
346 --iter-time 5000 --use-urandom -y luksFormat /dev/sdaX
347 #+end_src
348
349 where =/dev/sdaX= is the partition you created in the last step
350 (e.g. =/dev/sda4=). For more information about the =cryptsetup=
351 options, see the [[https://wiki.archlinux.org/index.php/Dm-crypt/Device_encryption#Encryption_options_for_LUKS_mode][LUKS encryption options]].
352
353 Then we open the container:
354
355 #+begin_src bash
356 cryptsetup open --type luks /dev/sdaX lvm
357 #+end_src
358
359 Now it's time to use lvm and prepare the logical volume(s):
360
361 #+begin_src bash
362 pvcreate /dev/mapper/lvm
363 vgcreate vg /dev/mapper/lvm
364 lvcreate --extents +100%FREE -n root vg
365 #+end_src
366
367 This will create a physical volume on the mapping we just opened,
368 create a volume group named =vg= on the physical volume, and create a
369 logical volume named =root= that spans the entire volume group. More
370 complex setups are possible thanks to the great flexibility of lvm.
371
372 We now format the logical volume with =ext4=:
373
374 #+begin_src bash
375 mkfs.ext4 /dev/mapper/vg-root
376 #+end_src
377
378 *** Installing the base system
379
380 Let's mount the logical volume, make a directory for the mount point
381 of the boot partition, and mount the boot partition (=/dev/sda1=):
382
383 #+begin_src bash
384 mount /dev/mapper/vg-root /mnt
385 mkdir /mnt/boot
386 mount /dev/sda1 /mnt/boot
387 #+end_src
388
389 Finally, let's install the base system (and optionally =base-devel=):
390
391 #+begin_src bash
392 pacstrap /mnt base base-devel
393 #+end_src
394
395 *** Configuring the system
396
397 Let's generate the fstab:
398
399 #+begin_src bash
400 genfstab -U /mnt >> /mnt/etc/fstab
401 #+end_src
402
403 Use your favorite terminal-based editor, edit the fstab file and add
404 the =discard= option for the root partition to enable TRIM on the SSD.
405
406 Now we change root into our newly installed system and will configure
407 it. Adjust these according to your own setup.
408
409 #+begin_src bash
410 arch-chroot /mnt /bin/bash
411 passwd # set the root password
412 echo myhostname > /etc/hostname # set the hostname
413 ln -s /usr/share/zoneinfo/Canada/Eastern /etc/localtime # time zone
414 hwclock --systohc --utc # write system clock to hardware clock (UTC)
415 useradd -m -G wheel -s /bin/bash myuser # create myuser
416 passwd myuser # set the password for myuser
417 echo "myuser ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers.d/myuser
418 # uncomment en_US.UTF-8 UTF-8 and other needed locales in /etc/locale.gen
419 locale-gen
420 echo LANG=en_US.UTF-8 > /etc/locale.conf
421 export LANG=en_US.UTF-8
422 #+end_src
423
424 Then adjust the initramfs hooks in =/etc/mkinitcpio.conf= and enable
425 the =encrypt= and =lvm2= hooks, and make sure =keyboard= is available
426 before =encrypt= so you can actually type in the LUKS password when
427 booting. Your =HOOKS= line should look similar to this:
428
429 #+begin_src
430 HOOKS="base udev autodetect modconf block keyboard encrypt lvm2 filesystems fsck"
431 #+end_src
432
433 After adjusting the hooks, build the initramfs:
434
435 #+begin_src bash
436 mkinitcpio -p linux
437 #+end_src
438
439 Now, install the =intel-ucode= package. We'll configure the bootloader
440 to enable intel microcode updates.
441
442 #+begin_src bash
443 pacman -S intel-ucode
444 #+end_src
445
446 Create the =/boot/loader/loader.conf= with the following content
447 (adjust the timeout to your liking):
448
449 #+begin_src
450 default arch
451 timeout 3
452 #+end_src
453
454 Then create the entry for Arch:
455
456 #+begin_src bash
457 mkdir -p /boot/loader/entries
458 touch /boot/loader/entries/arch.conf
459 #+end_src
460
461 Now edit =/boot/loader/entries/arch.conf= to specify the Arch entry:
462
463 #+begin_src
464 title Arch GNU/Linux
465 linux /vmlinuz-linux
466 initrd /intel-ucode.img
467 initrd /initramfs-linux.img
468 options cryptdevice=/dev/sdaX:vg:allow-discards root=/dev/mapper/vg-root rw
469 #+end_src
470
471 Again, =/dev/sdaX= is the partition you created in the [[#partitioning][partitioning]]
472 step as the underlying encrypted partition.
473
474 Finally, install the bootloader, exit the chroot, umount and reboot!
475
476 #+begin_src bash
477 bootctl install
478 exit
479 umount -R /mnt
480 reboot
481 #+end_src
482
483 *** Post-installation recommendations
484
485 Congratulations! You now have a minimal Arch installation.
486
487 At this point, I usually install my favorite AUR helper, [[https://aur.archlinux.org/packages/pacaur/][pacaur]], then
488 I install the [[https://aur.archlinux.org/packages/broadcom-wl-dkms/][broadcom-wl-dkms]] wireless driver and [[https://aur.archlinux.org/packages/mba6x_bl-dkms/][mba6x_bl-dkms]]
489 backlight driver to fix the post suspend/resume issue where three's no
490 brightness after waking up from suspend, and the only available
491 brightness would be 100%.
492
493 #+begin_src bash
494 pacaur -S linux-headers dkms # linux-headers is required for dkms
495 pacaur -S broadcom-wl-dkms
496 pacaur -S mba6x_bl-dkms
497 #+end_src
498
499 Then, I'd like to install
500
501 - input, graphics, and sound drivers,
502 - a desktop environment (I prefer Xfce or LXQt),
503 - a display manager for login screen (lightdm or sddm), and
504 - a network manager (NetworkManager or ConnMan).
505
506 Check out the [[https://wiki.archlinux.org/index.php/General_recommendations][General recommendations]] for more details.
