If you check Fedora and the various RHEL and RHEL-clone lists, you'll
find that there are people who ask about having problems mounting nfs
shares from fstab and that it works for them once they add "_netdev"
to the options. Ubuntu's mountall has its own "bootwait" but it
understands "_netdev" too.

By the way, you've probably used upstart on Fedora and RHEL. Fedora
switched to upstart with F9 and Red Hat switched to upstart with
RHEL6, based on F12/F13. Neither of them made as much of a switch as
Ubuntu (which itself didn't go fully native) and they only (1)
replaced sysvinit's "/sbin/init" and (2) used upstart jobs to start
the ttys and to run "/etc/rc.d/rc.sysinit" and "/etc/rc <runlevel>"
(and to go to the rescue or emergency runlevels, if requested).
