The above is exactly right - for a Debian system. Possibly also for any
Debian-derived system (e.g. ubuntu). But Fedora sets up networking
differently than this.
For Debian users, you can also put this into /etc/network/interfaces:
auto eth0
iface eth0 inet manual
That essentially changes eth0 operation into a noop. The reason this
might be desirable over simply omitting eth0 is that other parts of the
Debian boot process might depend on eth0 actually being up'ed first -
triggering the various nearby if-up.d scripts. I hit this problem when
trying to set up another NFS client mount.
I've been writing up a long page describing all the fun I've had in
setting up diskless PXE-booted read-only NFS-rooted frontends. The
writeup isn't finished, but the trick above is in there. The URL for
the page is here:
