Making ntsysv/chkconfig compatible rc scripts

To make a startup/shutdown script that can be used with ntsysv or chkconfig, the script must follow the template:
#!
#
# chkconfig: runlevel startpriority stoppriority
# description: brief, possibly multi-line description \
# follows

For example:
#!/bin/bash
#
# Init file for OpenSSH server daemon
#
# chkconfig: 2345 55 25
# description: OpenSSH server daemon


Sharing the GNOME desktop

GNOME now has a built-in VNC service called vino. It's there in Applications->Preferences-> Remote Desktop. Unlike VNC server, the display number used with this desktop is :0.

Resizing mounted partitions

Starting with kernel version 2.6.10, you can resize ext3 partitions using resize2fs program (part of e2fsprogs). While resize2fs could be used to shrink and grow ext3 partitions, the one bundled with e2fsprogs-1.36+ can apparently resize even mounted partitions! Woo hoo!
