Public bug reported:
Hi folks,
While doing a routine update of my system, update-initramfs yelled at
me, complaining about my EFI partition not found.
Except it was there.
Don't know if it's a dracut problem or something else.
The error in question:
update-initramfs: Generating /boot/initrd.img-6.17.0-14-generic
I: The initramfs will attempt to resume from /dev/dm-1
I: (/dev/mapper/gandalf--vg-swap_1)
I: Set the RESUME variable to override this.
Couldn't find EFI system partition. It is recommended to mount it to /boot or
/efi.
Alternatively, use --esp-path= to specify path to mount point.
gandalf in ~ via 🐍 v3.13.7
at 14:53:26 ❯ mount | grep fat
/dev/nvme0n1p1 on /boot/efi type vfat
(rw,relatime,fmask=0077,dmask=0077,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro)
Could be something, could be nothing. I didn't spot anything suspicious in my
logs. The error persists when running update-initramfs manually (via sudo
update-initramfs -u -k all).
