Yes, because there is no concept of single user mode to the kernel.

It isn't that being in multi user mode causes a problem as such, it's because something happens when you run /etc/rc which causes the problem. Your example doesn't say why you need to be in single user mode when using geli.. The only reason you need to be in single user mode during an upgrade is so that running programs don't find libraries ripped out from under them and then they crash. In that case you don't need to reboot into single user mode, you just make sure there aren't any non-kernel processes (besides sh) which are running. -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
