Bug#860458: mdadm: please make it possible to create an initramfs without mdadm support

Package: mdadm
Version: 3.4-4+b1
Severity: normal

It seems that if you want to have mdadm installed but not present in the
initramfs then the only option is to remove the mdadm files from under
/usr/share/initramfs-tools.  Otherwise you get a larger initramfs and some
delay while it tries to assemble a mdadm that may not be possible.

Here are some situations where you want mdadm installed but not in the
initramfs:

Making a recovery disk that needs to be able to access raid etc but not for
booting.

Running a system that has /boot on software RAID and / on some other form of
RAID (such as BTRFS or ZFS).  Especially if that system has VMs that use
the same initramfs and have no software RAID because they have virtual devices
from BTRFS or ZFS filesystems.

Running a system with limited disk that needs to connect to arrays
occasionally, such as using a laptop with a single internal disk to connect to
RAID arrays and test them.
