This covers obtaining the ISO, connecting to Wi-Fi, partitioning, formatting, mounting, installing, setting up encryption and installing GRUB, in one article. Also includes some tips, like quickly mounting from install medium. Maybe this helps someone.
The biggest problem I have with full disk encryption is that there’s still no way to include /boot into the BTRFS root partition for snapshotting. Having your kernel images separate from your system snapshots makes rolling back massively painful.
You might install an older kernel version from
/var/cache/pacman/pkgand then regenerate the initramfs. If not using NVIDIA, it’s very easy to have multiple kernels installed (e. g. linux, linux-lts) to have another option if one kernel causes trouble.I’d generally recommend having the lts or mainline kernel additionally if you use custom kernels, like zen or self compiled
