Post installation shell

[Robert Simmons]

I've just finished getting everything right for installing to a geli
encrypted root partition.  This requires the use of the shell in the
installer during the disk partitioning stage and at the end of the
install process.  I've run into a problem:

If you enter the shell at the end of the install process, the shell is
now chroot'ed to the newly installed partition that was mounted on
/mnt.  The problem with this is that the functional /dev directory is
inaccessible.  The /dev directory that is accessible is empty!

This is not that big of a deal since, the very next thing the
installer offers you is the live-cd, which is not chroot'ed to /mnt it
is back to where you would expect it to be.

Is this something that perhaps should be mentioned in documentation?
