change is fine, but I dunno why we do type rootdev after calling rootdev.  The
only reason the type rootdev was in there is because chromeos-setimage used to
be called in the chroot for image_to_vm, and there was no rootdev command. (The
line is pointless now :)

     # Enable verification, but don't force a check for dev builds.
     if rootdev | grep -qE '^/dev/(dm-|mapper/)'; then
       rootfs_verification_default=${FLAGS_TRUE}
