Bug#239111: grub-install still hangs

[Gregor Jasny]

Hi,

today I've migrated my system from ext3 to xfs. When I tried to install grub 
via grub-install --recheck /dev/hda the install process hangs. An apt-get 
update process in another terminal began to hang too. I think it tried to 
write into the frozen root filesystem. So I opened a new terminal and 
executed xfs_freeze -u /boot/grub. After this command my system was working 
again.

Imho grub tries to write to some file in the root filesystem during install 
(i.e. a new device map). Because the filesystem is frozen it deadlocks.

If you need more info please contact me.

Cheers,
Gregor
