Hello Arne,

The will have their reasons, why the developers choosed 300 MB as
minimum file system size. Even there is this flag to bypass that, may
there as you already mentioned unexpected side effects.

This would be a good idea, because the kernel size grows up from
release to release and if there are strange out of space problems in
the past would solve them too. Enlarge to for example 512MB would solve
both issues at once.

Are there any problems to expect for small installations on very
limited storage space (SD-cards etc.) ?

This would bypass the XFS limitation but would result in a kind of
very fragmented filesystem types. EFI would be vfat, boot ext4 and if
selected the main file systemd XFS.

I would no expect any troubles when doing this but for me it tastes a
bit dizzy and unclean.

In theory there would be a fourth option:

4. Drop the option to select XFS during setup and force the usage of
ext4....
