Linus named the upcoming 4.0 release of the kernel “Hurr Durr I’ma
Sheep” (see his git commit), so we are celebrating this April Fool’s
day with a minor prank. If you’ve been redirected to
imasheep.hurrdurr.org, do not panic. It’s all part of the joke.
We’ve also restored all FTP and Rsync access to the
mirrors.kernel.org servers, as we seem to have resolved our SSD
and dm_cache problems. If you’re still using FTP, however, please
consider switching to HTTP. FTP is a protocol designed for a different
era — these days everyone should be avoiding it for multiple
reasons.
