The man who in every sense sits at the nerve centre of SUSE Linux has no airs about him. At 38, Vojtch Pavlk is disarmingly frank and often seems a bit embarrassed to talk about his achievements, which are many and varied. He is every bit a nerd, but can be candid, though precise. As director of SUSE Labs, it would be no exaggeration to call him the company's kernel guru. Both recent innovations that have come from SUSE - patching a live kernel, technology called kGraft, and creating a means for booting openSUSE on machines locked down with secure boot, have been his babies.
