Hello Developers and Contributors.
I have found the culpable one: DASH !!!
I was wondering, WHY some of my programs/scripts do not more work,
even if I have "#!/bin/bash" in the first line... first I was
thinking it is XTerm which eat my Environement... No, it isnt.
Running 'pstree -Alpancu michelle.konzack |xmessage -file -' from
a button in fvwm give me
bash,3983
`-startx,4171 /usr/X11R6/bin/startx

Midnight\040Commander -name mc -n mc -e /usr/bin/mc
`-mc,6016
`-bash,6018 -rcfile .bashrc
which looks realy normal... but hold, PID 4186 is 'sh'
which is a symlink to dash. Whenever I start a command
like 'Exec xterm' from within fvwm it invokes /bin/sh
which eat the environement...
Changeing the symlink back to 'bash' as under Woody my
whole environement is working again...
I can now use TMPDIR and MANPATH without any problems and
headstandings.
Maybe the $USER schould be informed of this behaviour...
or by installing DASH, debconf should inform the $USER,
that some programs will have some strange behaviour...
Or better, the X-Window-System should use the $SHELL
variable from the $USER, if started with 'startx'.
