To get rid of this, login once as user 1 password is AMANAGER, then 
restart as some other user number

Some AIPS routines assume that the user number is <= 4 digits and 
smaller numbers may be easier to remember

This causes an error below - the data area # 8 /arlstorage/ etc does not 
have write privilege for you.  I recommend either fixing that or taking 
the area out of your list of disk areas ($NET0/DADEVS.LIST).

The 2 "errors" above are **** from a format not large enough for a 5 
digit user number and ZOPEN from your lack of write access to disk area 
8.  It could not create a CA file for you there.  I suspect that my 
diagnosis below is actually correct.  DO NOT access your Linux areas 
with your Solaris machine.
