package: os-prober
version: 1.64
Os-prober doesn't notice initrd files other than debian's one.
In a partiion I've Slackware. I created a initd.gz for slaclware
(generic kernel needs a initrd for ext4 module, if not I receive
a kernel panic) and tried to make grub set it from debian.
Please, consider
1) in Slackware partition there is a initrd.gz
===========================================
root@debian:~# ls /mnt/slackware/boot/
config elilo-ia32.efi inside.bmp System.map

efi
===========================================
2) os-prober doesn't notice it:
===========================================
root@debian:~# os-prober
/dev/sda2@/EFI/Microsoft/Boot/bootmgfw.efi:Windows Boot Manager:Windows:efi
/dev/sdc4:Slackware Linux (Slackware 14.1):Slackware:linux
===========================================
and after, to control:
===========================================
root@debian:~# linux-boot-prober /dev/sdc4
/dev/sdc4:/dev/sdc4::/boot/vmlinuz-generic-3.10.17::root=/dev/sdc4
/dev/sdc4:/dev/sdc4::/boot/vmlinuz-huge-3.10.17::root=/dev/sdc4
===========================================
3) update-grub2 obviuosly doent's set that initrd:

===========================================
i dont' understand why it's impossible to choose
between huge and generic kernel, and above all why
it lacks all occorrences of initrd
