Added sometime round April > http://svn.freebsd.org/viewvc/base/head/sys/geom/sched/README?view=log It's been pointed out on the list a couple times, and I've sent mail to the authors about this, that gsched breaks (very, very badly) things like sysinstall, and does other strange things like leaves trailing periods at the end of its ".sched." labels. This appears to be by design, but I'm still left thinking "?!" It's hard to discern technical innards/workings of GEOM since the documentation is so poor (and reading the code doesn't help, especially with regards to libgeom). IMHO, the gsched "stuff", as a "layer", should probably be moved into the I/O framework by default, with the functionality *disabled* by default and tunables to adjust it. That's just how I feel about it. -- | Jeremy Chadwick jdc_at_parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
