optional client cert issue

[jcline]

Thanks Michael for jumping on this. Without baking in a trusted root I get a http://ipxe.org/err/420c60 (broken pipe) - unfortunately without much more info. I'll try flipping debug on here and see if I can get any more details. Also instead of doing a chain I'll try doing an imgfetch and imgstat, see if I can kinda bisect the problem a little. If we get there I'll try adding the cert and see what happens.

Any other debug suggestions?
