"Normal" reading of a cleanly-unmounted filesystem will do fine. It's just
the edges that will cause problems, things like:
- do sparse files work correctly ?
- do files that posix_fallocate(3C) was used on work correctly ?
- does it deal with the Solaris Multi-TB UFS extension ?
- does it deal with non-clean filesystems that use logging ?
- can it handle filesystems that went through growfs(1M) ?
- can Linux access e.g. a SVM metadevice with a UFS on it ?
- can you access/honour UFS ACLs ? xattrs ?
If all you want is a small filesystem to export a bit of data from Solaris
to Linux, it's ok. But Linux UFS support (in all variants) was and is
labeled "EXPERIMENTAL" for a reason.
