I started a port of Fossil to plan9port few months ago.

It seems to be working fine, but:

 - the console doesn't work,
 - it doesn't handle Plan 9 partitions tables,
 - I haven't wrote the manuals.

I hope to fix all of these problems in the future. The lack of
console is obviously a big issue.

Beware this is not exactly the Plan 9 Fossil. This is the modified
Fossil I use on Plan 9. This Fossil is based on libventi and
libthread, instead of liboventi.
This is why liboventi haven't been ported.

I considered it is too experimental to be submitted to plan9port,
but the patches are available online:

 - [1] fossil-plan9: import Fossil from Plan 9,
 - [2] fossil-new: modified Fossil,
 - [3] fossil-new-p9p: required plan9port changes on Fossil.

However, I recently submitted two needed patches to libventi:

 - [4] libventi-redial: add redial and reconn functions,
 - [5] libventi-noarchive: add VtEntryNoArchive.

These two patches add features, currently part of liboventi,
missing from libventi, but useful to Fossil.

If you want to contribute, I will be happy to receive patches
and bug reports.
