Control: tag -1 patch * Steve Graham <b...@annaghvarn.plus.com> [2014-08-16 13:27 +0100]:
> I also have a system with no LVM requirement.
>
> The lines "/proc/devices: No entry for device-mapper found" are emitted by
> grub-probe. In general, the grub scripts redirect grub-probe's stderr to
> /dev/null to suppress these, but the subroutines in
> /usr/share/grub/grub-mkconfig_lib aren't completely consistent in doing so.
>
> I quickly hacked /usr/share/grub/grub-mkconfig_lib to add the redirection on
> every invocation of grub-probe and the messages have gone away.
>
> For example, the original line
> partmap="`"${grub_probe}" --device $@ --target=partmap`"
> was changed to
> partmap="`"${grub_probe}" --device $@ --target=partmap`" 2> /dev/null

Attached patch I've successfully tested on i386_soft-raid,
amd64_one-disk, amd64_LVM_soft-raid and ppc_one-disk
