Thanks for this.  After adding the secret dependecy "crc32c" to the 
initrd.kernelModules I got my system booting.

One question remains, how do I get fsck.btrfs available on bootup?

btrfsprogs provides btrfsck on my system profile.  Do I have to use 
boot.initrd.extraUtilsCommands to copy it by hand to the initrd?
