Please update this bug report when os-prober is fixed. Suggested solution is OK.

Debian bug report for linux-boot-prober (in package os-prober): https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=820838

Some distros, e.g. Manjaro, use multiple paths on the initrd line.
Including only the first results in a kernel panic rather than booting.

30_os-prober fails to account for the possibility of multiple initrd paths: if linux-boot-prober gives it multiple paths, separated by spaces, 30_os-prober will remove the spaces and replace them with carets ("^").

The whole system is a hack, but a simple fix is to replace the carets with spaces again, as it does for some of the other fields:

http://git.savannah.gnu.org/cgit/grub.git/tree/util/grub.d/30_os-prober.in
line 210:
- LINITRD="`echo ${LINUX} | cut -d ':' -f 5`"
+ LINITRD="`echo ${LINUX} | cut -d ':' -f 5 | tr '^' ' '`"

NB: linux-boot-prober currently outputs only the first path on the initrd line, even when multiple paths are present. This bug is being reported separately to the maintainers of os-prober (debian-boot). The simple fix suggested above assumes that their solution to this bug will be to space-separate multiple paths.
