Hi Muli,
I doubt it (did you try it?).
Now I tried it, on Fedora Core 4 (on x86).
It works like a charm! feel free to try it ...
Aftrer applying the patch and "modprbe ufs" I ran that series of commands,
but mkfus like this :
/mkufs -O 1 /test/disk-image
Rhere was no error in mount , and
running now
"mount | grep ufs
shows it is OK:
/test/disk-image on /loopDir type ufs (ro,loop=/dev/loop0)
BTW, I tried also mount -r -o loop -t ufs /test/disk-image /loopDir
and it did perform mount OK, only the kernel log says
Sep 26 20:43:29 localhost kernel: You didn't specify the type of your
ufs filesystem
Sep 26 20:43:29 localhost kernel:
Sep 26 20:43:29 localhost kernel: mount -t ufs -o
ufstype=sun|sunx86|44bsd|ufs2|5xbsd|old|hp|nextstep|netxstep-cd|openstep
..
Sep 26 20:43:29 localhost kernel:
Sep 26 20:43:29 localhost kernel: >>>WARNING<<< Wrong ufstype may
corrupt your filesystem, default is ufstype=old
When trying the same but with
/mkufs -O 2 /test/disk-image
I get that error in mount:
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
and in the kernel log : kernel: ufs_read_super: bad magic number
As for the reason why UFS1 works and UFS2 not,
I will try to hack the code a bit and post my thoughts tomorrow or in two days.
I think we should remeber that ufs
support in the linux kenel is a bit problematic. We can mount ufs only
as a read only
filesystem in linux ; this was once the case with NTFS , now it is a
bit better , but also
when you mount an ntfs from linux , it might not succeed.
In their own words:
"Note: That doesn't mean it always succeeds, it is still experimental
and might just as well refuse to complete an operation in order to
prevent corruption. "
see :
http://www.linux-ntfs.org/
And looking from the opposite dircetion (namely , an
operating system which comes with ufs like solaris/*BSD) :
There is a solaris package to mount ext3 and ntfs from solaris ufs;
see: http://www.genunix.org/distributions/belenix_site/
It mounts EXT2FS and NTFS partitions, but as read-only partitions.

I doubt it (did you try it?). It's obvious from the kernel log that
fs/ufs gets super block magic number 0, which is wrong any way you
look at it.
Cheers,
Muli
