Ah, yes, that makes more sense.

I do have package and the rules:
gargamel:~# dpkg -L btrfs-tools 
/.
/lib
/lib/udev
/lib/udev/rules.d
/lib/udev/rules.d/80-btrfs-lvm.rules
/lib/udev/rules.d/70-btrfs.rules

But it's very possible that udev isn't working properly or timely on
this system.

I added "btrfs device scan" to /etc/init.d/cryptdisks

Thanks for the help.
