Thank you Joyent!
Joyent posted an update -- they've released a branch of illumos , on github, containing much of their illumos contributions. Some of the stuff is probably fairly Joyent specific, but some of it is highly useful to almost everyone using illumos! From their mail: ZFS I/O fair-share scheduling for zones the Joyent brand, which can be used as a template for other non-SysVR4 or IPS zone brands Reintroduction of sparse zone images Crossbow vnics on demand for zones & non-unique vnic naming (unique per zone, not per system) svcs enhancements ( svcs -Z/-z for interrogating zone services, -L for outputting log files directly (no more ls /var/svc/log | grep... )) vfsstat and iostat tweaks and ziostat, iostat(1M) for ZFS I/O more per-zone IO kstats the zonemon utility for zone kernel state troubleshooting DTrace enhancements such as llquantize I just want to say again, thank you very much Joyent! Now, how quickly can we merge this stuff into illumos mainline?
