Re: Error mounting LVM volume as root (SOLVED)

Indeed, I have found that `/dev/<VG>/<LV>` doesn't work as argument to
`root=` on the kernel command line, whereas `/dev/mapper/<VG>-<LV>`
works fine.

Maybe it merits a bug report.  Maybe it'll be hard/inconvenient to make
the kernel accept the `/dev/<VG>/<LV>` form, but if so scripts like
`upgrade-grub` could come to the rescue and either warn about the
problem or do the rewrite themselves.
