Well that must have been a very very old kernel then, at least if you intend to insist on blaiming DEVFS. See cvs logs. >> History being rewritten eh ?

It was an interesting first impression. A lot of people, you included, have never quite realized, or maybe just forgotten exactly just how long time Julians DEVFS sat in our tree while people bickered about things like "persistence" and random panics: src/sys/miscfs/devfs/devfs_vfsops.c: Revision 1.1 Thu Apr 20 03:31:31 1995 UTC (6 years, 3 months ago) by julian After 3 years I gave up on the hope that it would ever be fixed well enough to become politically acceptable. After 6 years I removed it. A quick script run on the cvs tree paints this picture of number of commits to src/sys/miscfs/devfs per year: julian phk other 1995 56 3 15 1996 20 10 43 1997 21 13 16 1998 15 2 24 1999 6 15 30 2000 0 16 8 2001 0 1 7 -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
