In the interest of minimising maintenance, we're going to stop maintaining Ken's fs and IL entirely. We thank them (and Ken) for many years of faithful service. We're now running fossil with nventi on our main file servers. cwfs(4) now exists, so old juke boxes are still accessible.
This does not mean that you need to stop running Ken's fs, just that we're going to remove /sys/src/fs and /sys/src/9/ip/il.c from the distribution, and that a replica/pull in the near future may remove them from your system, so you may want to rename them or make copies beforehand, or copy them out of the dump afterwards. If anybody wants to maintain Ken's fs and keep copies in sources/contrib (for example), that's fine. I've put a snapshot of the current /sys/src/fs in /n/sources/extra/kenfs.tgz.
