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.
