I, Serge Hallyn, apply for core-dev.

Who I am

I am a member of the Ubuntu Server Team, employed by Canonical. I'm involved with packaging of libvirt, qemu, lxc, and cgmanager, am the Debian maintainer for netcf, and on the debian packaging team for qemu.

My Ubuntu story

My interest first shifted from sunos to linux when I got involved in kernel development. The ability to modify my own kernel was a huge freedom. I started with slackware, moved to redhat, then gentoo, and finally Ubuntu. My shift to Ubuntu was at first practical, because it was the most likely at any time to 'just work' on any given laptop.

In 2010 I joined Canonical to work on Ubuntu full time, with the server team.

My involvement

Examples of my work / Things I'm proud of

The heaviest packaging work I've done has been the migration from qemu-kvm+qemu-linaro to a mostly-in-sync-with-debian qemu. I'm one of the Ubuntu and upstream maintainers for lxc, having in my previous life worked on namespaces in the kernel. I introduced apparmor and seccomp support as well as the new C API in lxc. I also helped to shepherd the shadow changes needed to support unprivileged user namespace use into upstream, debian and Ubuntu, which are instrumental in unprivileged lxc use. I was the author and uploader of cgmanager (motivated by lxc) and it's dumber older brother cgroup-lite (motivated by libvirt).
