Re: ufs problem (mounting ufs under linux-2.6.0-test11)

[Jan.Stary@ff.cuni.cz]

Hello,

I don't seem to be able to mount the FreeBSD-5.1-RELEASE's ufs
partition in linux-2.6.0-test11, which occupies another partition
on the same machine (which is Acer Aspire 1304XC).

Has the ufs format changed in 5.1? I specify ufstype=44bsd in
the mount command.

	Thank you

Here it goes (/var/log/syslog):

:"ufs_read_super: bad_magic_number" is a very odd behaviour :-(

Yes. I am using the partition for my BSD boots happily, though -
maybe the ufs has changed in freebsd 5.1 ? I will ask on the BSD
list.

	Thanks for your time, Heiko.
