Then how should we deal with, say, /usr/bin/ssh which is imported from
OpenSSH? The original version (2.3.x) is needed to leave? Or use only
our version like 1.5.0.x? IMHO, original versions have less meaning in
terms of making system consistent. (This is applied to pkgsrc, too.)

...And, if we will have a version for /usr/bin/ssh, we may be able to
specify versions on announcements, and any other documents...
