kesboot's Issues
incompatible efibootmgr output
i don't know why, but the output of efibootmgr (from manjaro-linux) is something like this:
$ efibootmgr
BootCurrent: 0002
Timeout: 1 seconds
BootOrder: 0002,0006
Boot0002* Linux Boot Manager HD(1,GPT,7ff6991c-d9ef-4c3e-8bf1-345168f07626,0x800,0x100000)/\EFI\SYSTEMD\SYSTEMD-BOOTX64.EFI
Boot0006* UEFI OS HD(1,GPT,7ff6991c-d9ef-4c3e-8bf1-345168f07626,0x800,0x100000)/\EFI\BOOT\BOOTX64.EFI0000424f
So the entries won't end with the name and kesboot is unable to found his own entries.
so i added the following line in main.sh:_get_efi and main.sh:_get_efi_num to get rid of the tabulator and the rest of the line and to make it work as expected:
_poses="$(echo "$_poses" | sed 's/\t.*//')"
pacman uninstall hook missed kernel with prefix
when uninstalling a kernel, the efi-var can't be found:
# mhwd-kernel -r linux67 ✔
...
:: Pre-transaction-Hooks werden gestartet …
(1/3) Removing linux initcpios...
(2/3) Updating EFI variables (remove)...
Can't find the builduser kernel in the EFI variables...
...
if i read the source correctly, "builduser" should be the name of the kernel to be removed?
lsblk -r -n -o PARTUUID <device> doesn't work via arch-chroot
In a "recovery" environment (i.e. an archiso boot + arch-chroot), lsblk -r -n -o PARTUUID /dev/nvme0n1p1 yields an empty string for me. By contrast, blkid -o value -s PARTUUID /dev/nvme0n1p1 works as expected.
Pacman hook adding wrong cmdline pair
Hi,
I was trying to switch to dracut from mkinitcpio but I found that the kesboot pacman hook keeps adding '*' to the CMDLINES array and failing.
---> New kernel: *
kernel "*" not found!
It works when I use mkinitcpio, so I'm not sure if it's a dracut issue or kesboot issue
Adding second initramfs for microcode
Hi, I can't see an obvious way to add a second initramfs for microcode other than by inserting directly into the cmdline array. This is obviously not the preferable solution - if this functionality existed and I'm missing it or could be added that would be great. Many thanks!

Incompatible with root in btrfs subvolume
When creating an entry for a root installed in a btrfs subvolume, the entry stays with empty root and doesn't add the subvol argument:
lsblk: /dev/nvme0n1p2[/@root]: not a block device
lsblk: /dev/nvme0n1p2[/@root]: not a block device
Clears CMDLINES array elements on kernel upgrades
- Vanilla Arch Linux
- kesboot version:
1.9.r0.g2d8eae8-1(up-to-datekesboot-gitfrom AUR) - 2 installed kernels (
linuxandlinux-mainline) - booster as initramfs generator
Every time I upgrade my kernel packages, e.g. linux, the CMDLINES element for that kernel simply is removed and replaced with 'linux' '' at the end of the array.
Relevant parts of upgrade log where this issue happened:
:: Running pre-transaction hooks...
(1/3) Removing linux booster images...
(2/3) Updating EFI variables (remove)...
===> Removed linux

Doesn't work with BTRFS
When running keboot -u I get [root@scott-laptop ~]# kesboot -u lsblk: /dev/sda2[/@]: not a block device lsblk: /dev/sda2[/@]: not a block device lsblk: /dev/sda2[/@]: not a block device lsblk: /dev/sda2[/@]: not a block device
and in CMDLINE options it says root=PARTUUID= which makes it fail to boot.
