Kickstart broken on Ubuntu 11.10 beta: calls missing watershed

[Floris]

Kickstart LVM is broken on Ubuntu 11.10

While doing the "clearpart" step, it tries to call /lib/udev/watershed, which doesn't seem to exist in the Ubuntu 11.10 netboot initrd.

There is a watershed-udeb, but it does not seems to get installed when you use netboot.

Watershed is called by the rules file /lib/udev/rules.d/85-lvm2.rules which belongs to the lvm2-udeb

==
SUBSYSTEM=="block", ACTION=="add|change", ENV{ID_FS_TYPE}=="lvm*|LVM*", \
 RUN+="watershed sh -c '/sbin/lvm vgscan; /sbin/lvm vgchange -a y'"

Perhaps a depdency on the watershed-udeb should be added to the control file of lvm2-udeb?
Or udev rules without watershed should be used? (Debian seems to have different rules, that do not call it)
