I do not believe so. For example, this is from my running system:
joe@jmorris:~> ls -l /dev/disk/by-uuid/
total 0
lrwxrwxrwx 1 root root 10 2009-01-09 13:20 801c2029-6789-4117-a461-da745a19f062
-> ../../sda1
lrwxrwxrwx 1 root root 9 2009-01-09 13:20 a2d3f2bf-eaec-45a0-b843-55b15f037d83
-> ../../md0
lrwxrwxrwx 1 root root 10 2009-01-09 13:20 a97bf970-827c-458d-8d59-764fc0381da8
-> ../../sdb1
lrwxrwxrwx 1 root root 10 2009-01-09 13:20 e3e86c6b-4445-4611-90a8-fb7b2df6e5af
-> ../../sda7

Even though my home is on md1, as you can see above it is still absent in
by-uuid. I believe md0 is only there because of the added
sleep 1
echo change > /sys/block/md$md_minor/uevent
that I added to boot-mount.sh See Comment #19.

But, looking around at /dev/disk/by-id, I see:
joe@jmorris:~> ls -l /dev/disk/by-id/
total 0

Which at least recognizes md1 as well as md0, though I am not sure how that
would change the fact that the file system info is still not output, which is
what is causing this part to fail, i.e.

jmorris:/home/joe # udevadm info -q env -n /dev/md0
MD_LEVEL=raid1
MD_DEVICES=2
MD_METADATA=0.90
MD_UUID=ffb096e5:5d1a78ab:71771454:6b84c526
ID_FS_USAGE=filesystem
ID_FS_TYPE=ext3
ID_FS_VERSION=1.0
ID_FS_UUID=a2d3f2bf-eaec-45a0-b843-55b15f037d83
ID_FS_UUID_ENC=a2d3f2bf-eaec-45a0-b843-55b15f037d83
ID_FS_LABEL=root
ID_FS_LABEL_ENC=root
ID_FS_LABEL_SAFE=root
jmorris:/home/joe # udevadm info -q env -n /dev/md1
MD_LEVEL=raid1
MD_DEVICES=2
MD_METADATA=0.90
MD_UUID=50317547:316ba81e:fc3a8342:011169ec
MD_DEVNAME=1

Without the ID_FS_TYPE info the fsck cannot work and stops booting.
