Creating a core dump / backtrace from /bin/login

[Till Maas]

Hiyas,

pam_mount is crashing /bin/login under special circumstances when I login via 
a text console and I would like to get a backtrace. In a recent thread using 
a core dump was suggested for a crashing window manager, but it was needed to 
run a "ulimit -c unlimited" or similiar to get the core dump in the shell 
before the window manager is started. But how can I do this for /bin/login?

Regards,
Till
