Bug#815555: initramfs-tools: raid1 boot with lilo fails on 0.123 with cant find root in fstab

[Ben Hutchings]

Control: retitle -1 Numeric root device IDs are resolved too early since 0.123
Control: severity -1 important

Downgrading this because it only affects LILO configs where root is
specified as /dev/md0 (which is deprecated) and not by UUID.

Bug#815555: initramfs-tools: raid1 boot with lilo fails on 0.123 with cant find root in fstab

[Anders Nyvang]

Hi again

I have now tried switching to Grub2. This boots perfectly on the same
setup. Also after upgrading to initramfs-tools 0.123.

So this is going to be my workaround for the time being. And if grub
behaves, I am probably not going back to lilo.

What filesystem type is the root mounted with, when you use
initramfs-tools 0.120?  (Check in /proc/mounts.)

What does '/usr/lib/klibc/bin/fstype /dev/md0' show?

What does 'blkid /dev/md0' show?

Ben.

Bug#815555: initramfs-tools: raid1 boot with lilo fails on 0.123 with cant find root in fstab

[Anders Nyvang]

Package: initramfs-tools
Version: 0.123
Severity: critical
Justification: breaks the whole system

Dear Maintainer,

After updating from 0.120 to 0.123 my system cannot boot.

System is software raid1 and booting with lilo.

Post up to the initramfs prompt:
BIOS data check successful
mdadm: /dev/md0 has been started with 2 drives.
modprobe: module unknown not found in modules.dep
mount: can't find /root in /etc/fstab

... and the errors goes on, but primary relates to the fact that the root 
filesystem is missing.

I have recreated the issue on my virtualbox Debian Stretch (where this report 
is created).
Compare files and lsinitramfs without any luck.

Cheers,
Anders Nyvang
