Failed systemd-boot upgrade... how to rescue?

hendry · 2015-08-05 07:15:54

On my NUC, I recently updated from Systemd 223 to 224 with a kernel upgrade too.. from 4.1.3-1-ARCH to 4.1.4-1-ARCH IIRC. However something has gone wrong and I am wondering if I can recover it from systemd-boot? Any tips to pick out the fallback kernel maybe?

Otherwise I guess I will be trying to fix from this from installation media.

Chroot in and make sure /boot is mounted when you upgrade your kernel (which it was not).

Moving to NC...

That's probably the cause. Thought I wonder why I can't boot successfully the old kernel and initramfs in that case?

When you say "Chroot in"... from the installation media, right? I can't somehow rescue the situation with some cmdline editing, can I?

It is simplest just to chroot from a live media and reinstall linux and the regenerate the initramfs.

Ok, I ended up copying /boot to /dev/sda1 and then fixing up fstab. Some notes:

- Console font on the live media is WAY too small and I couldn't install terminus via pacman
- dosfslabel didn't work
- options suggested by https://wiki.archlinux.org/index.php/Fstab for EFI /boot rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro is kinda extreme.

Still find it a bit worrying that my old kernel failed to boot. Also wondering how I should put my root partition in my /etc/fstab.
