| Note for the pdksh -> mksh transition                         |
+---------------------------------------------------------------+
| If you have any user accounts with /bin/pdksh as login shell, |
| change these to /bin/mksh because pdksh will be replaced by a |
| symlink to lksh, a variant of mksh used to run legacy scripts |
| but not suitable for interactive use. For sane defaults, also |
| have users copy /etc/skel/.mkshrc into their home directories |
| and unset ENV. This warning will only be shown this once.     |

# dh_installdeb will replace this with shell code automatically
# generated by other debhelper scripts.
