Bug#678262: mdadm: fails to honour INITRDSTART='none' in /etc/default/mdadm

[Chris Donoghue]

Package: mdadm
Version: 3.2.5-1
Severity: critical
Justification: breaks the whole system

Dear Maintainer,

It looks like the /usr/share/initramfs-tools/hooks/mdadm fails to honour
the setting of INITRDSTART='none' in /etc/default/mdadm which led to an unbootable
system. 

The initramfs panic'ed from the script in 
/usr/share/initramfs-tools/scripts/local-top/mdadm.

It does continue on when the exiting out of the initrd dropped to shell.

With none setting that above files are put in the initrd

$ lsinitramfs /boot/initrd.img-3.2.0-2-amd64  | grep mdadm

etc/mdadm
etc/mdadm/mdadm.conf
sbin/mdadm
scripts/local-top/mdadm

Which aren't required at all in mdadm isn't required to be started at initrd time.


I added at line 80 of /usr/share/initramfs-tools/hooks/mdadm

[ $INITRDSTART = "none" ] && exit 0

which allowed my system to boot through fine.

But these still leaves me with

$ lsinitramfs /boot/initrd.img-3.2.0-2-amd64  | grep mdadm

sbin/mdadm
scripts/local-top/mdadm

Which aren't needed due to no requirement of mdadm in initrd.


Thanks


Chris
