Re: Root password problem (fwd)

[rzbz13%punkass.com@localhost]

Thanx for the help, problem solved. I had Kinkos print out
the guide for me, but I must have missed the appropriate
section. I think I need to do some rereading. I was long
overdue to change my password anyway, still haven't figured
that part out yet.
Thanx again, Rob

This smells of a minor bug ... the file is not busy, it just
cannot be opened for writing.  The bug is in the error message,
it is correct for passwd to fail here.

Use vipw for this, not vi.  vipw will take care of resynchronizing the
files involved.

This is from vi.

Export an appropriate value for TERM.  "vt100" typically works.
(# export TERM=vt100)

This is often done in root's .whatever (.profile, .shrc, .login...
others depending on shell)

During boot, and in single user, / is mounted read-only.

Before invoking vipw  (I assume NetBSD has this vipw), remount
/ to be writeable.  (mount -u -w / )  If /var is on a separate
filesystem, it may need to be mounted; you may be seeing a shadow,
rump /var under the / filesystem.  I suspect this is not your
case, though.  Perhaps /var is mounted readonly, if so, that must
be changed.  I don't have a NetBSD system handy at the moment.

It sounds as if all your files are on one file system, namely "/".
Usually /var, /usr, /home are not mounted when in single user.
(Although you may mount them if you wish.)

It is possible that root logins are disallowed for the terminal
at which you are logging in.   In OpenBSD, this is controlled
by /etc/ttys.  See man 5 ttys or the NetBSD FAQ.

Try again in single user, do "mount -u -w /" and try vipw
or passwd.  Somehow I think your passwd database is screwed
up, possibly by using vi on /etc/master.passwd instead of vipw.
A command, /usr/sbin/pwd_mkdb, synchronizes /etc/passwd and
/etc/master.passwd (OpenBSD, Net assumed the same -- check
before trusting), vipw calls this among other niceties.
