Okay.., I took the view that following the Handbook was the way to go, chan= ging "*default release=3Dcvs tag=3DRELENG_5" to "*default release=3Dcvs tag= =3DRELENG_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 n= ow need to configure, compile and install a custom kernel. But when I check= ed the location of where (the default in FreeBSD) I'd expect to see a new G= ENERIC, 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 MYKERN= EL to add / delete as required, as well as remove the debugging statements = that I'd come across from reading various suggestions (like "options INVARI= ANTS", etc), but I've found that the GENERIC on this system doesn't have th= e 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 E= xp $ 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 device= s. makeoptions DEBUG=3D-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 direct= ories 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 NFSCLIE= NT options MSDOSFS # MSDOS Filesystem options CD9660 # ISO 9660 Filesystem options PROCFS # Process filesystem (requires PSEU= DOFS) options PSEUDOFS # Pseudo-filesystem framework options GEOM_GPT # GUID Partition Tables. options COMPAT_43 # Compatible with BSD 4.3 [KEEP THI= S!] options COMPAT_FREEBSD4 # Compatible with FreeBSD4 options COMPAT_FREEBSD5 # Compatible with FreeBSD5 options SCSI_DELAY=3D5000 # Delay (in ms) before probing SC= SI 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 exte= nsions options KBD_INSTALL_CDEV # install a CDEV entry in /dev options AHC_REG_PRETTY_PRINT # Print register bitfields in debug # output.
