Package: initramfs-tools
Version: 0.120
Severity: normal
Dear Maintainer,
copying a Jessie installation from a server with hardware raid to a
system with software raid /dev/md* I found that the system would not
start on the new machine and would get stuck in initramfs.
Looking at /proc/mdstat and using blkid I found that all software raid
devices were available and their UUID could be found. Only symlinks to
the devices in /dev/disk/by-uuid/ were missing.
Setting the missing symlink to the root-filesystem manually and exiting
initramfs shell led to normal system boot.
Looking into the problem I found that in file
/usr/share/initramfs-tools/hooks/udev a wrong filename prevents
/lib/udev/rules.d/63-md-raid-arrays.rules from being copied to the
initramfs.
A temporary solution without edditing files owned by the package is
putting the following script into e.g.
/etc/initramfs-tools/hooks/udev-fix-md-boot:
=========================== cut here ============================
#!/bin/sh -e
PREREQS=""
prereqs() { echo "$PREREQS"; }
case "$1" in
prereqs)
prereqs
exit 0
;;

. /usr/share/initramfs-tools/hook-functions
mkdir -p $DESTDIR/lib/udev/rules.d/
rules=63-md-raid-arrays.rules
if [ -e /etc/udev/rules.d/$rules ]; then
cp -p /etc/udev/rules.d/$rules $DESTDIR/lib/udev/rules.d/
elif [ -e /lib/udev/rules.d/$rules ]; then
cp -p /lib/udev/rules.d/$rules $DESTDIR/lib/udev/rules.d/
fi
=========================== cut here ============================
For a final fix a change of /usr/share/initramfs-tools/hooks/udev is needed:

With either solution after rebuilding initramfs with 'update-initramfs
-k all -u' the system booted without problems using the software-raid
/dev/mdX as root filesystem identified by its UUID.
