That brings up a topic that I'd started in this group about 2 weeks ago when I had a similar "difficult" experience using the "fixit" procedure after booting from CD. I ended up getting the CD's MAKEDEV to work after I un-hard-coded /sbin/mknod ... much more difficult than it should be me thinks. I intend on working on the problem and contributing a chapter to the handbook on "using the fixit disk" but didn't want to push things as we were going through the release cycle. I want Jordan to get some needed sleep before I spam him and the rest of the list with what-if questions regarding the fixit floppy, etc. (for instance, MAKEDEV has a special "fixit" ``target'' with comments saying "gotta reduce devices to save precious inodes" ... so the natural inclination of making "sh MAKEDEV all|fixit" create the slice entries seems like that won't work). More in a few days after 4.1-R excitement dies down a bit. -Jr -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= | John Reynolds WCCG, CCE, Higher Levels of Abstraction | | Intel Corporation MS: CH6-210 Phone: 480-554-9092 pgr: 602-868-6512 | | jreynold@sedona.ch.intel.com http://www-aec.ch.intel.com/~jreynold/ | =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
