Hello everyone,

i've installed Debian's root tree on encrypted partition. The kernel asks password; "Enter passphrase to unlock /dev/...". I would like to know where, and in what source files, is this part, eg password prompt. This system uses 2.6.26-1 kernel, i've searched the source in crypto, fs, device-mapper parts and no luck. I've even grepped the whole tree, still can't find it.

Basically, i would like to implement another way of getting passphrase, not via keyboard prompt. Therefore, a simple answer : where the hell is this thing, and if it ain't in kernel source, how can i rebuild the kernel with my changes

Thank you in advance.

Sounds like the LUKS prompt. You can use a keyfile instead of a keyboard prompt. Look for or try "man" cryptsetup. The command should be in your initrd file if nowhere else...
