/usr backup/remove issue

[Mike Fern]

hi all,

i have freebsd 5.1 running with 4 x 200GB ATA HD. let's say i have
/usr installed in hd1. i want to move /usr to a larger partition in
hd4. how can i do that?

here is my scenario. i backed up all /usr data to /usr1 in hd4. then i
checked the location of ln and mkdir to make sure that they are not
located in /usr. after that, i deleted or files in /usr "rm -Rf /usr"
and planned to create symbolic link from /usr1 to /usr. anyway, lately
i realized this is really stupid idea. after rebooting, i couldn't log
in to terminal. even logged in as single user didn't help. (i tried
mount the partition, but was nothing to avail).

anybody can shed a light?

thanks before.
Mike
