It turns out when you run debmirror on CentOS 7 from EPEL, it sneakily (not really) lays down a configuration file in /etc/debmirror.conf. Despite the ‘-d‘ argument, e.g. ‘-d xenial,xenial-security,xenial-updates‘, it happily tries to mirror the sid distribution.

How do you improvise what you need to treat that person and make it possible to move them? When I was growing up in a rural […]

One day they decide to upgrade their customers to VDSL2, send out BEC Technologies BEC 8920NE gateways to the customer, and now use PPPoE. Your old ADSL2 modem […]

So yeah, I’m still around! I have a month off from work so I’ve been bumming around from one thing to another. My truck just rolled 300,000 miles recently and I finally got around to having * replaced as part of regular maintenance. I’ve been wanting to head off on some roadtrips but not really […]

My colleague Matthew gave a presentation about bare metal provisioning servers at Facebook on IPv6-only networks at SREcon last month. He discusses the entire process from why we went v6-only, selection of DHCP server and network boot loaders, through installing CentOS on hosts, and all of the gotchas along the way. By audience survey it […]
