[PKG-Openstack-devel] Bug#825352: fuel-umm: fails to install in chroot: /usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?).

Package: fuel-umm
Version: 9.0+dfsg1-2
Severity: important

Hi,

during a test with piuparts I noticed your package failed to install in
a chrooted environment. It might work on real metal.

>From the attached log (scroll to the bottom...):

  Selecting previously unselected package fuel-umm.
  (Reading database ... 
(Reading database ... 7804 files and directories currently installed.)
  Preparing to unpack .../fuel-umm_9.0+dfsg1-2_all.deb ...

  Setting up fuel-umm (9.0+dfsg1-2) ...
  /usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?).
  dpkg: error processing package fuel-umm (--configure):
   subprocess installed post-installation script returned error exit status 1
  Errors were encountered while processing:
   fuel-umm

You probably need some guard around the grub-probe call.
Check the grub packages how they handle this situation.
ischroot might be helpful, too.

cheers,

Andreas
