I know that mounting a UFS from a readonly media recently seems not to work (but in 2.2.1 times i managed to dump a UFS partition to a CD and was also able to mount the CD as UFS and read from it) cheers luigi To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
