Dear Aips-meisters

We have a multi-workstation install of aips, and all workstations
share disks with one another via nfs. The 'master' machine is called ATLAS.
Yesterday I inadvertently deleted these two files
       /AIPS/DA00/ATLAS/GRD000000;
       /AIPS/DA00/ATLAS/PWD000000;
and this resulted in all sorts of havoc. The host subdirectories in DA00 all
have a link to these files, e.g.

atlas% ls -l  /AIPS/DA00/PUPPIS/GRD000000\;
 lrwxrwxrwx   1 aipsmngr aipsusr       31 Jan  2 16:16
          /AIPS/DA00/PUPPIS/GRD000000; -> /nfs/AIPS/DA00/ATLAS/GRD000000;

I was able to repair things by copying /AIPS/31DEC99/SOL/GRD000000\; and
PWD000000\; into the right place, but I have no idea why this helped,
apart from allowing the symlink chain to be resolved.

Can you explain to me what the function of these files is please?
