I think we're going to have to agree to disagree on this, since I must
admit that my reaction to the above analysis is basically eye-rolling. :)
Forking off a uname -a in parallel to the rest of what's going on during
boot is not going to be noticable. I think you are doing quite a lot of
premature optimization here.

Ah, no, I was responding specifically to your suggestion to replace
pam_motd with pam_issue. Unless that module does something different than
what its man page says it does, I don't believe this is possible.
