In any case I always get a ufs1 fsck error after the Linux rm and rmdir.
Interesting... Could you put together an image (starting with zeroing the
device before newfs, and ideally with dd from /dev/zero to create files)
that would
a) pass fsck on OpenBSD
b) after rm on Linux fail the same
then convert it to qcow2 and publish? Or just compress it - all free and
data blocks would contain only zeroes, so any kind of compression (gzip,
bzip2, whatever) would reduce the size to something more managable...
I created a gzip and sent you an email with the link to a UFS1 OpenBSD
filesytem image.
I finished simple testing of UFS1 with FreeBSD and NetBSD and found no
problems except for the differences between "available" blocks in df
commands.
And testing UFS2 was fine with all 3 systems, FreeBSD, OpenBSD and
NetBSD.
