I'm dealing with mobile devices (laptops, etc), ergo I need an automount
solution. I've been using automounter happily for removable devices, but
users are picky and I then can't use amd for nfs and automounter
couldn't give a shit about network drives. One scenario is network goes
down and I get a screenful of error messages- it annoys the shit out of
me, let alone scaring illiterate users.
I did come across one interesting observation in my search for the
truth: its easier to mount a winblows share than an nfs one! On any *nix

Already done, but that doesn't help automounting.

Interesting theory, but it doesn't hold water. More further...

They don't care too much under linux either.... So many years, yet not a
single user doc anywhere on any of the f***ing monsters! Goddamn linux
devs- ever heard of KISS?! How about a user doc for something so bloody
confusing it takes a brain surgeon to figure it out?
Ok. The final cut... I did finally get hal/polkit/dbus to cooperate in
the end. But there were more suspects by the end:
exec xhost +localhost &
## test for an existing bus daemon, just to be safe
if test -z "$DBUS_SESSION_BUS_ADDRESS" ; then
## if not found, launch a new one
eval 'dbus-launch --sh-syntax --exit-with-session'
echo "D-Bus per-session daemon address is: $DBUS_SESSION_BUS_ADDRESS"
exec /usr/local/libexec/polkit-gnome-authentication-agent-1 &
exec xscreensaver &
exec ck-launch-session icewm-session
So... one needs to start a local dbus session, a polkit-auth session,
and a ck-launch-session...
And in PolicyKit.conf (I'm not entirely happy with the security here),
scratch user or group matches and just add the action with result=yes.
Now that will work in a single user situation. There is yet another
culprit here: gconf. GConf was the shooter on the grassy knoll causing
issues with the mount options and permissions.
And the crazy part in all this is there is hardly a scratch of info out
there on such complex software that are supposedly interacting together
in some way that is not exactly documented and yet is in control of the
whole bloody system! We should just all revert to winblows at this rate-
there's more docs there than for this stuff! An absolute embarrassment
to the FOSS community...
Ahh, one more thing of note here: polkit-gnome-authorization would not
work under any circumstances (run as root or otherwise) to change

Oh, believe me I'd happily jump on it rather than deal with this mess.
But I can't find anything that will interact happily with the apps,
mount network shares of all kinds, and be exceedingly user friendly
(take note lin-devs: user-friendly != sys_admin-hell at least it
_doesn't have to_).
How forgiving is devd to a user pulling the plug to early? I did look
into it a bit, but it appeared nearly as difficult as deciphering the
above scenario- that said, having come through the other side of that
I'm not so sure my judgment was very accurate :) So now I might check
that fork out and see...
God! What a mess... this belongs in the X-files: the truth _is_ out
there. But you might lose your head and many years of life just finding
HTH someone now when the whole lot will change yet again and this will
probably be pointless...
