/rescue/vi doesn't work without /usr (no terminal db)
I just booted into single user on a 5.4-p6 system. I needed to edit something on the root fs, but /rescue/vi wouldn't work, it complained about not finding the terminal database. I saw some mention in the archives from June about fixing this, though I don't think anything has been comitted yet. In the meantime, how can I run /rescue/vi without /usr? thanks, Thomas -- N.J.

It only needs a read-only /usr though, so if /usr is a local filesystem you can probably get away with: # mount -o ro /usr ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

This time it was, so I got away with it. But I did find this in rescue(8) however: BUGS Most of the rescue tools work even in a fairly crippled system. The most egregious exception is the rescue version of vi(1), which currently requires that /usr be mounted so that it can access the termcap(5) files. Hopefully, a failsafe termcap(3) entry will eventually be added into the ncurses(3) library, so that /rescue/vi can be used even in a system where /usr cannot immediately be mounted. In the meantime, the rescue version of the ed(1) editor can be used from /rescue/ed if you need to edit files, but cannot mount /usr. I don't know how old this note is, but I hope the failsafe termcap will be added soon. Thomas -- N.J.

Since it's just vi without graphics it shouldn't need a termcap (which doesn't mean it won't want one of course). What was $TERM set to? Having said that, I can still remember a time when any sysadmin worth tuppence would know how to use ed because that was all that worked on a teletype :-) --Alex ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

But when things have gone so wrong that you actually have to use the tools in /rescue, you are generally not in the mood to deal with something as archaic as ed. =-) Thomas -- N.J.
