You need to create a UFS1 file system.

Also, root file systems usually don't have soft updates (-U) enabled. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Hello, everyone. This is the problem: our SCSI disk with FreeBSD 4.8 on it has been failing recently, so I copied its root partition to a fresh IDE disk with cp -pR and You should use dump and restore to copy the root partition, see: I'd done that before trying cp -pR, as outlined by rse@: dump -L -0 -f- /old | (cd /new && restore -r -v -f-) http://people.freebsd.org/~rse/mirror/ which isn't too different.
