Interesting! when I check out the source package, and build with the
above patch and like this:
./configure CFLAGS="-g -O0" --disable-gtk-docs --enable-lvm2
make -j4
sudo src/udisksd -rd --force-load-modules
then it loads the module just fine:
(udisksd:17050): udisks-WARNING **: 14:52:41.121: Can't load configuration file
/usr/local/etc/udisks2/udisks2.conf
udisks-Message: 14:52:41.122: Loading module lvm2 ...
udisks-Message: 14:52:41.131: Acquired the name org.freedesktop.UDisks2 on the
system message bus
Curiously, when I run the exact same ./configure invocation that the
Debian packaging does, and run it out of the build tree, it works.
It does seem to be *something* about the built module, though -- with
the patch above (running modules from build tree) it works, but without
the patch it loads them from /usr and fails.

This keeps mystifying and evading me. More debugging tomorrow, but it's quickly
nearing the point where I run out of time to debug this.

Title:
loading lvm2 module crashes: udisks_module_lvm2_new: assertion
'UDISKS_IS_DAEMON (daemon)' failed
Status in udisks2 package in Ubuntu:
New
Status in udisks2 source package in Mantic:
New
Bug description:
I tried to do this with `apport-cli
/var/crash/_usr_libexec_udisks2_udisksd.0.crash`, but 's'ending
doesn't do anything obvious. I run this from a cloud image over ssh, I
really don't have any GUI. So filing this manually.
Trying to load the lvm2 module crashes udisks immediately:
