Oddly enough, I _think_ this is the intended behavior.  I had a similar
issue during Alpha, and it seems admins asked for a passphrase timeout
when activating any non-essential system partitions during boot.  The
timeout is in the minutes range, I forget if it's 1 or 3 minutes.  I'm
trying to re-familiarize myself with this issue, so don't quote me on
this yet! :)

Are you not encrypting your rootfs, or is the passphrase for the rootfs
and /home different such that you are always prompted for the /home
passphrase on boot?

Selinux sandbox (policycoreutils-sandbox) is responsible for making it
look like partitions are mounted twice.  Iirc, they are bind mounts.

Still trying to pinpoint this issue in
