[daip] installation problem on linux

[Eric Greisen]

chgrp has a recursive option

cd $AIPS_ROOT
chgrp -R aipsuser 31DEC07

should do it for the aips source code etc.

What will be more inportant are the data and DA00 areas. 

>From $AIPS_ROOT
cd DA00
chgrp -R aipsuser *

Note that file lockiong over nfs is still problematical in Linux (I
think) so it is better if the actual DA00 areas are on the host that
they are for.  So the directories in $NET0 (== $AIPS_ROOT/DA00) should
be link files to the actual hosts.  Similarly, the data areas may be
set up in many ways.  One that I like is in $AIPS_ROOT/DATA to make
symbolic link files to the actual data areas again on the host that
reall is going to use them.  The DADEVS.LIST file in $NET0 then points
to the DATA directories and via the link to the real ones.  It keeps
the structure more organized and a bit simpler that way.
