Re: automount /home maps?

Yes, Sidai has something (simple) -- the proto-package is
automount-maps [sidai/package/automount-maps.xml].
`glasli1' uses it, so you can see exact bits that we use --
its real package is also called automount-maps (and
inherits, of course, from sidai:automount-maps).

Automount maps can come from *.tmpl files (see
glasli1/automount-maps/*.tmpl, for example) or can be
generated from a set of 'dchunks' info, or both.  ('glasli1'
does both.)  At glasli1, as it happens, there is a 'users'
map (not a 'home' map), and it is simply a .tmpl file.
(Our 'd' and 'workspace' maps are generated from dchunks.)

The 'configure' method (by default) groks the dchunks stuff,
to produce a 'super-tmpl' file, automount-maps.tmpl.

The 'compile' method produces per-host automount maps,
either from the generated automount-maps.tmpl file, or from
the hand-written *.tmpl files.  When that's done at glasli1,
I end up with the files listed below.

We then get these files into place (/etc on each host) using
the normal sidai:ark-diffing-deploy machinery (install,
deploy, reveal).

When we make changes to the maps, we run

  sidai/package-utils/ark-invasive automount-maps

to re-do things.  All kinda low-tech, but does what we want.

If you were doing NIS -- we don't at glasli1 -- you'd want
to set your own <hosts-supported>, probably to something like
(e.g.) sparc-solaris7-nis-server, and probably have other
packages (nis-server-config? nis-client-config?) that dish
the bits out from there.

(I'll turn this message into the missing documentation :-)

I would be happy to elaborate the Sidai automount-map
package a little to cater for (a few) other common
practices...
