Items in the Debian alternatives system are kept in
/etc/alternatives/ as symlinks.
To set your favorite X Window environment, apply
update-alternatives to /usr/bin/x-session-manager and
/usr/bin/x-window-manager. For details, see Custom X sessions, Section 9.4.5.1.
/bin/sh is a direct symlink to /bin/bash or
/bin/dash. It's safer to use /bin/bash to be
compatible with old Bashism-contaminated scripts but better discipline to use
/bin/dash to enforce POSIX compliance. Upgrading to a 2.4 Linux
kernel tends to set this to /bin/dash.
