Me, having been at nanog all day, where I accidentally wiped out my
vpn servers (while having a deep conversation about quagga),
simultaneously terrified of losing the mail server and trying to fix
it..., and now (11PM PDT) having succeeded in uncrashing the email
server, and sorted through a zillion documents on how to do antispam,

vpn partially, and nuked 27,000 files that were clogging up the
...am going to bed. (after driving 2 hrs home).
It would have been nice to have got the "fedora 22 uses fq_codel by
