Package: grub-common
Version: 1.99-22
Severity: normal
When update-grub is running,
it also calls os-prober, and it looks that it tries to check what is on
my ZFS partition, but fails to do this.

grub-mount sits there forever, and if I want to cleanly shutdown
and unmount my zfs partition (I use zfs-fuse), i need to kill it.
Here is strace log
