Subject: Use login shell for session

Date: Fri, 24 Jan 2020 21:19:03 -0700

[Message part 1 (text/plain, inline)]

Package: x2goserver
Version: 4.1.0.3
Tags: patch

X2Go's Xsession file always starts the user's session with /bin/bash (at 
least on RedHat systems where SHELL is set to /bin/bash via ~/.bashrc 
calling /etc/bashrc).  This patch attempts to determine the user's login 
shell and use that for launching the session.  See also:

 https://bugzilla.redhat.com/show_bug.cgi?id=1794660

Another option might be the judicious use of the --norc option when 
launching x2goruncommand on followers but I'm not sure what other 
effects this will have or where to do that.  Effects might not be to bad 
because I can simulate this by moving away the user's .bash_profile and 
.bashrc files and then the tcsh is used as expected in this case. 
However, while $SHELL does not get set in this case, the xfce4-session 
script still gets launched with bash which triggers some other errors, 
so this patch may be the best option.

    x2goserver-xsession/etc/Xsession: Detect $SHELL from getent passwd and use it to launch the session (on RHEL, SUSE, Gentoo and alike). (Fixes: #1434).

     least on RedHat systems where SHELL is set to /bin/bash via ~/.bashrc
     calling /etc/bashrc).  This patch attempts to determine the user's login
     shell and use that for launching the session.  See also:

     Another option might be the judicious use of the --norc option when
