Out of space in /boot due to initramfs-linux-fallback.img

Hey folks,

i have a dual boot Arch/Win11 and currently can't update either because /boot is full. This is due to initramfs-linux-fallback.img being 134M, while the total size of /boot is 240M.

Some options I have seen in my research in the wiki/forum:

1) Resize /boot
Unfortunately this is tricky because the adjacent partition is an MSR (Microsoft Reserved). Not sure how to deal with this, if possible at all.

2) Compress initramfs by using COMPRESSION_OPTIONS in mkinitcpio.conf
Wiki says it can be dangerous. Is it?

3) Disable the generation of initramfs-linux-fallback.img
Not sure if there's any downside to this?

4) Create an additional partition and move initramfs-linux-fallback.img there
My preferred option so far, since everything works as usual (I hope!). My understanding is that I'd have to update arch.conf (I'm using systemd) to load from the new partition. My biggest question here is what happens upon linux update: will the fallback image be created in the new partition as well? If not, should I change linux.preset to point to the new path? If I do, will linux.preset be overwritten at any point in time (e.g. by updates)?

Open to other suggestions as well!

Thanks!

I had a similar problem and went with option 3. The issues faced in the past required a live boot media anyway so the fallback was never helpful
