Re: (hopefully perl) API to /etc/network/interfaces?

Yes, I absolutely need to change the boot config.  The endpoint for the
tunnel to purgatory needs to follow purgatory every where purgatory
goes, even after a reboot.

The running config can be altered by rebooting, however I was just going
to ifdown/up.  Now I'm contemplating either running the commands to
alter the running config VS ifdown, change boot, ifup.

# Used by ifup(8) and ifdown(8). See the interfaces(5) manpage or
# /usr/share/doc/ifupdown/examples for more information.
# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
# Uncomment this and configure after the system has booted for the first
time
