Clears CMDLINES array elements on kernel upgrades

[JamiKettunen]

• Vanilla Arch Linux
• kesboot version: 1.9.r0.g2d8eae8-1 (up-to-date kesboot-git from AUR)
• 2 installed kernels (linux and linux-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:

(2/3) Updating EFI variables (remove)...
===> Removed linux

'linux' ''

Sorry for such a late response, there were some things to do. So far, I do not know how to solve this problem, since during the Upgrade operation, the pacman launches the Remove hook anyway. The only solution at the moment is to disable the kernel removal hook. REMOVE_HOOK=1

I found out about CMDLINE_DEFAULT afterwards and since I planned to use same cmdline for both I'm happy enough with using that instead; this still remains an issue though indeed if you want to use different cmdlines
