I like the direction.

The more dangerous commands usually require a --force option on other
tools. (fsck, mkfs, rpm, drbdadm, ...)

For cibadmin, -E, -r, (-b, -h, -l for write commands) seem safe
candidates.

Reading y/n from stdin is not a good approach; the commands might
require the XML to be on stdin.
