.attwtmp on OSx 2.5

info-pyramid@ucbvax.UUCP (12/23/85)

We are running a Pyramid 90x under OSx 2.5.  For some reason,
/etc/.attwtmp grows in size until it fills up the file system.  This
happens after less than a day of uptime.  We have attempted to disabled
the accounting from the rc files but with the same results.  What program
or part of the system controls .attwtmp?  Is there a way to fix the
problem?  Are other sites having the problem?  Any information would be
helpful.  Thanx.

The att universe keeps its records of logins/logouts/reboots/date(I)
changes in /etc/wtmp (linked to /etc/.attwtmp).  This file is
read with "att who /etc/wtmp."

The ucb universe uses /usr/adm/wtmp (linked to /etc/.ucbwtmp) for
logins/logouts. This file is read with "ucb last."

I think that /bin/login writes to both of these files, which
makes sense since a user in either universe should be able to
see records of users in both universes.   Our .attwtmp is 2.7M
long since September, but we don't do lots of loggin in/out
here.  Anyway, if you delete it all you will lose is a record
of who has been logged in.  It will probably come back.  I guess
you could symbolically link it to /dev/null.
