NetApp Training Brain Dump: /etc/rc

Interesting history:

"The letters stand for Run-Com, the name of a command
file on early DEC operating systems. The Unix system's
original "rc" file was /etc/rc, which executes commands
when the system "boots" (or starts up). The name spread
to the C shell startup file .cshrc, the Mail startup
file .mailrc, the Berknet initialization file .netrc,
and the Netnews startup file .newsrc. Programmers could
have chosen a better suffix (such as init) but they
wanted to retain a realm of mystery in the system."
