Package: grub-common
Version: 1.98-1
Severity: normal

First noticed within the past week while trying to upgrade memtest86+,
the grub-probe program complains:
grub-probe: error: cannot find a device for / (is /dev mounted?).

It gives the same error when invoked directly from the command line.
/dev is, in fact, mounted.  The output of mount shows:
/dev/mapper/c--68--40--176--142-root on / type ext4 (rw,user_xattr,errors=remount-ro)
Verifying that with file gives:
/dev/mapper/c--68--40--176--142-root: symbolic link to `../dm-0'
And verifying that gives:
/dev/dm-0: block special
