Okay.., I took the view that following the Handbook was the way to go, changing "*default release=cvs tag=RELENG_5" to "*default release=cvs tag=RELENG_6". All went fine, that is, I was able to cvsup sources to upgrade a FreeBSD-5-Stable machine to FreeBSD-6.0-RC-1: $ uname -a FreeBSD <snipped> 6.0-RC1 FreeBSD 6.0-RC1 #0: Sun Oct 30 16:09:08 GMT 2005 <snipped>:/usr/obj/usr/src/sys/GENERIC i386 $ All looks well, whereby I can log in successfully, and load X as before (I know that at some point I need to rebuild all installed ports), however I now need to configure, compile and install a custom kernel. But when I checked the location of where (the default in FreeBSD) I'd expect to see a new GENERIC, I see the following: /usr/src/sys/i386/conf $ ls -tla total 92 drwxr-xr-x 2 root wheel 512 Oct 30 18:05 . drwxr-xr-x 14 root wheel 512 Oct 29 19:48 .. -rw-r--r-- 1 root wheel 1741 Oct 29 19:48 GENERIC.hints -rw-r--r-- 1 root wheel 372 Oct 28 20:21 DEFAULTS -rw-r--r-- 1 root wheel 10211 Oct 28 20:21 GENERIC -rw-r--r-- 1 root wheel 33284 Oct 7 15:00 NOTES -rw-r--r-- 1 root wheel 322 Sep 18 04:37 SMP -rw-r--r-- 1 root wheel 1766 Jul 29 17:02 PAE -rw-r--r-- 1 root wheel 13 Jun 20 17:52 .cvsignore -rw-r--r-- 1 root wheel 120 Feb 26 2003 Makefile /usr/src/sys/i386/conf $ After copying GENERIC to "MYKERNEL", I'd have expected to go through MYKERNEL to add / delete as required, as well as remove the debugging statements that I'd come across from reading various suggestions (like "options INVARIANTS", etc), but I've found that the GENERIC on this system doesn't have the entries for any of those debugging statements to remove. Here's a snippet where I'd have expected to see some of those entries: $ more GENERIC # # GENERIC -- Generic kernel configuration file for FreeBSD/i386 # # For more information on this file, please read the handbook section on # Kernel Configuration Files: # # http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig-config.html # # The handbook is also available locally in /usr/share/doc/handbook # if you've installed the doc distribution, otherwise always see the # FreeBSD World Wide Web server (http://www.FreeBSD.org/) for the # latest information. # # An exhaustive list of options and more detailed explanations of the # device lines is also present in the ../../conf/NOTES and NOTES files. # If you are in doubt as to the purpose or necessity of a line, check first # in NOTES. # # $FreeBSD: src/sys/i386/conf/GENERIC,v 1.429.2.4 2005/10/28 19:21:27 jhb Exp $ machine i386 cpu I486_CPU cpu I586_CPU cpu I686_CPU ident GENERIC # To statically compile in device wiring instead of /boot/device.hints #hints "GENERIC.hints" # Default places to look for devices. makeoptions DEBUG=-g # Build kernel with gdb(1) debug symbols #options SCHED_ULE # ULE scheduler options SCHED_4BSD # 4BSD scheduler options PREEMPTION # Enable kernel thread preemption options INET # InterNETworking options INET6 # IPv6 communications protocols options FFS # Berkeley Fast Filesystem options SOFTUPDATES # Enable FFS soft updates support options UFS_ACL # Support for access control lists options UFS_DIRHASH # Improve performance on big directories options MD_ROOT # MD is a potential root device options NFSCLIENT # Network Filesystem Client options NFSSERVER # Network Filesystem Server options NFS_ROOT # NFS usable as /, requires NFSCLIENT options MSDOSFS # MSDOS Filesystem options CD9660 # ISO 9660 Filesystem options PROCFS # Process filesystem (requires PSEUDOFS) options PSEUDOFS # Pseudo-filesystem framework options GEOM_GPT # GUID Partition Tables. options COMPAT_43 # Compatible with BSD 4.3 [KEEP THIS!] options COMPAT_FREEBSD4 # Compatible with FreeBSD4 options COMPAT_FREEBSD5 # Compatible with FreeBSD5 options SCSI_DELAY=5000 # Delay (in ms) before probing SCSI options KTRACE # ktrace(1) support options SYSVSHM # SYSV-style shared memory options SYSVMSG # SYSV-style message queues options SYSVSEM # SYSV-style semaphores options _KPOSIX_PRIORITY_SCHEDULING # POSIX P1003_1B real-time extensions options KBD_INSTALL_CDEV # install a CDEV entry in /dev options AHC_REG_PRETTY_PRINT # Print register bitfields in debug # output.
