I'm asking because ext4, when used without a journal, seems to be a worthy
replacement and has 64 bit dates.
I'll be happy to send a patch to fs/ext2/Kconfig to warn users.
For all practical purposes I agree we expect users to use ext4 driver on a
filesystem without a journal instead of ext2 driver. We are still keeping
ext2 around mostly as a simple reference filesystem for other fs
developers. I agree we should improve the kconfig text to reference users
to ext4.
Regarding y2038 problem - this is really the matter of on-disk format as
created by mke2fs, not so much of the kernel driver. And the kernel will be
warning about that when you mount ext2 so I don't think special handling is
needed for that.
you shouldn't create filesystems with a on-disk format that don't
support 64bit timestamps no matter how small the filesystem is
the arguments on this list where "such a small filesystem isn't expected
to be still used in 2038" which is nonsense in case of a /boot FS in a
virtual machine
our whole servers already survived 16 years and 30 dist-upgrades
