Unfortunately, my experience is that sysadmin required tools are not
well codified by POSIX.    I vaguely recall Solaris going from
/etc/fstab to /etc/vfs/???? between 1.x and 2.x.    In the end, it
depends on whether you are a "cookbook" style admin or someone who
tries to understand exactly what each command is accomplishing.  If
you are the later, it's often just a matter of figuring out what new
files have essentially the same configuration options.  If you are the
former, then even switching between RHEL and Ubuntu could be
difficult.
