Is "aptitude" a CentOS command? Gentoo? Ubuntu only?

It's been ages since I installed and configured Bind, but if you run Bind locally, shouldn't resolv.conf point to localhost? Also, aren't Linode's DNS resolvers datacentar-specific?

While I'm at it:

* timezone in a static networking script? and US only?
* rm and touch are redundant if you do cat >
* hostname should be taken out of fqdn automatically:

HOSTNAME=`echo $HOSTNAME_FQDN | awk -F"." '{print $1}'`

The "for Ubuntu Web Server" in the very first comment of the script seems pretty clear to me...

That said, I'm not sure that this script is the greatest idea. A static IP setup requires you to merely update a few config files, not to update packages or uninstall dhcpcd or install bind...

No error checking performed and no trap to stop the script if it encounters a problem. The 'rm' and 'touch' commands would also appear to be useless since you're overwriting the files anyway ( > ).
