When trying to emerge sys-fs/cryptsetup-luks-1.0.3-r2, I got the following output: ---------- * Checking for dm-crypt support ... [ !! ] * cryptsetup requires dm-crypt support! * Please enable dm-crypt support in your kernel config, found at: * (for 2.6 kernels) * * Device Drivers * Multi-Device Support * Device mapper support * [*] Crypt Target Support * * and recompile your kernel if you want this package to work with this kernel ---------- But I actually have dm_crypt compiled into running kernel.
