Bug#402087: xdm: "no home directory" test for Xstartup

[Phil Endecott <spam_from_debian_bugs_2@chezphil.org>]

Package: xdm
Version: 1:1.0.4-1
Severity: normal


/etc/X11/xdm/Xstartup includes a couple of commented-out lines that seem 
to have been intended to report a "no home directory" condition to the 
user.  I propose the following in their place:

# Warn if the user's home directory does not exist.
# It seems that $HOME is set to / after this script
# is executed, so we can't just compare $HOME with ~$USER.
if [ ! -d `eval echo ~$USER` ]
then
  xmessage "Home directory does not exist!"
fi


(In NFS environments, missing home directories are not uncommon.  Console 
logon reports the condition loudly.  In an Xsession the results can be 
odd, e.g. lost preferences.  Showing a message is important.)
