If people are chary about replacing autofs4 in its current shape with
some of the problems it has (like, if the process gets killed with busy
autofs4-mounted file systems), it's difficult to get the system back in
a working shape without rebooting.

Distros seeems to be using autofs3 all over the map, but I've found the
"use program" so very useful because it allows for the /etc/auto.net
stuff which is a great help in administration. To my surprise, I figured
that the FreeBSD amd(8) stuff (that I dropped a while ago because it was
inconvenient to administer and incompatible with Solaris) is capable of
doing these /net mounts as well, so I might just use a Makefile and go
amd again if Linux' autofs4 can't be made to fly.

It's fragile currently, and if there are changes that make the beast
solid, I'm all for it, and the whole discussion can be killed right here
because it's a "bugfix" in that case. After all, autofs4 is a
pre-something stuff and going "gold" is certainly a fix.

If there are optional features, well, they might have to be split out to
a separate patch or #ifdef'd out - but I direly hope that autofs4 will
improve.
