Hi,

what is the advantage of using /etc/crypttab?

When I was using it, I got errors during shutdown: "stopping early
crypto disks failed". This sounds sensible since the root-fs is
encrypted.

Now that I'm not using it, disks still get mounted on startup and the
error during shutdown is gone.

Is it ok to not use /etc/crypttab? I'd rather not use it, makes it
easier for me to synchronise /etc between different clients.

Thanks
Markus

My configuration: Debian Squeeze, cryptsetup 1.1.3, Kernel 2.6.32.
Im booting using an initrd. 
/dev/mapper/root_crypt is mounted on /
/dev/sda2 is mounted on /boot
