Good call, didn't think about doing that. I ended up using ts from
moreutils to get the same effect. Looks like flogin uses
"skip-page-display" and clogin uses "terminal length 0".
Skip-page-display takes 4 seconds to run. The majority of the slowness
in flogin appears to be the actual login process. Flogin is taking 20
seconds just to get to the enable prompt. Clogin is taking one second. I
haven't even started to look at why clogin/ssh works, but flogin/ssh
doesn't, which is how this whole thing started.
