I think it's more accurate to say they've changed the version numbering system these days. You even reflect it: Changing the minor number on 2.X (to 2.X+1) is similar to a major version number change these days. JKH even commented about getting the version number back when 3.0-RELEASE showed up. <mike > 1.X First public releases, based on BSD code later ruled "encumbered" > (ie: BSD 4.3) > > 2.0.X First major releases based on "unencumbered" code, ie: BSD 4.3 Lite > (in actual practice well over 90% of the code was left alone in > the conversion from encumbered to unencumbered) > > 2.1.X Releases finally reached the stability of the 1.X releases. > Probably last release you could tolerate in 4MB of ram. > > 2.2.X Major variance included introduction of Divert Sockets (for > natting and ipfw) > > 3.X Shredded the SCSI subsystem and replaced it with CAM, broke a lot of > older drivers, (arguably of junky hardware) introduction of Symmectric > Multiprocessing.

It should be on by default in GENERIC at some point. Like the CAM move, it broke old hardware (some of which is being resurrected). It also seems to have done a job on recording, but my best platform for checking that is having the issue confused by SMPng. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
