But if you have it working now without any initramfs then obviously that is full of win (the LA kind, not the Redmond variety)! I am a bit mystified -- or perhaps ignorant -- as to how it came to be that btrfs has no option to automatically initiate a scan (like md raid does, when it's built into the kernel as a non-module). Surely people must want that feature. I can see how scanning the wrong partitions could lead to terrible mayhem, though, say, in a disaster recovery scenario where you binary-cloned a failing drive and forgot to take the old one out before booting or whatever.... but btrfs has the secret sauce to most likely figure stuff like that out auto-magically anyhow, using the genid... so what gives? Anyone know? Perhaps the option really is there and I simply never found it; admittedly I didn't look very hard -- regardless, I can't imagine the btrfs people just "never thought of it". If i's really not implemented, there must be a reason... and if that reason doesn't apply to my situation I might consider patching such a feature into my kernels as this is the only thing tying my workstation to an initramfs. -gmt
