The directory did not exist, I created it.  On pretty much every machine
in the cfarm we have /opt/cfarm/ world-writable, it is quite handy (and
terribly insecure of course).

Of course it doesn't, running stuff from world-writable locations is
quite a leap of wait already, but doing that for every (perhaps even
typoed) command (by name!), well, that is ten steps too far for anyone's
taste.

There are no package managers.  Just "cp" or "mv" or something!

Mercurial is a challenge to build, yeah.
