Hello @all,
may it be possible to check in the preinstall routine of the package the
parameter size in mount of SHM ? (mount | grep shm | awk ...)
And if there is a limitation (parameter size is set) to create a message
to confirm for the user?
Because you can not upgrade from lenny to squeeze if there is this
limitation gnome-desktop (e.g. and all other mono based packages) does
not install correctly, it breaks the running system.
It is no a stopper for the release, but there is a simple check to
detect if there will or may be a problem.
And the fix is, just change the /etc/default/tmpfs to the new default
values 'SHM='. So no on else will have this problem or if he will have
a problem he got a message by installing or upgrading this package in
the console or his mails as package notification.

This was the first upgrade for me since Debian 3.0, which fails in such
a hard way.

Ok, I can finally reproduce and confirm this issue if shared memory (/dev/shm)
is exhausted. The mono runtime needs to deal with it though.
(I had to create a chroot btw, as the already mounted /dev/shm can not be
changed as long as it's used by some process)

As temporarily workaround MONO_DISABLE_SHM=1 as environment variable can be
used:
redbull:/# MONO_DISABLE_SHM=1 gacutil
The following assemblies are installed into the GAC:
redbull:/#
Considering that
1) there is a workaround
2) this seems hard to fix reliably, according to
https://bugzilla.novell.com/show_bug.cgi?id=662646#c1
I'm tagging this bug as not a blocker for the squeeze release.
Cheers,
Julien
