I guess it's trivial to fix, I usually overlook basic things...I installed Arch on encrypted LVM without issues, but for some reason initramfs doesn't ask for password to encrypted LVM and waits for root device instead. I'm not sure where the problem lies -- configuration files[1] seem correct to me.
Any ideas? [1] https://paste.xinu.at/pbiA78/ -- Bartłomiej Piotrowski http://bpiotrowski.pl/
