[SUMMARY] tip and /var

The question was how to recover tip connection that was broken when /var
was moved. 

Thanks to all who replied.

I got 3 replies. (I quoted them at the end of this email) I haven't
solved the problem, and am still searching for solution. 

By now I moved the /var disk completely, and I suspect perhaps the
incoming tip connection is not broken because of /var, since I tried
various things including:

fuser -k /dev/console
sacadm -a -p zsmon -t ttymon -c /usr/lib/saf/ttymon -v `ttyadm -V`
sacadm -k -p zsmon
sacadm -s -p zsmon

Right now this is where I stand.

# sacadm -l
zsmon          ttymon         -    0    ENABLED    /usr/lib/saf/ttymon #

# pmadm -l
PMTAG          PMTYPE         SVCTAG         FLGS ID       <PMSPECIFIC>
zsmon          ttymon         ttya           u    root     /dev/term/a - -
/usr/bin/login - 9600 - login:  - tvi925 -  #

but the incoming tip connection still does not work.

I posted a correction after getting Eric Voisard.
Could someone tell me what directories (under /var) sac or ttymon uses,
for an incoming "tip" connection?
If those files were "mv"ed to another disk and "ln -s"ed (symlinked) back
to /var, what is the proper way to restart related processes to have them
recognize the symlinking?

These are the replies I got.
