Вот последовательность действий: 1. pkg_add
ftp://ftp.freebsd.org/pub/FreeBSD/CVSup/cvsupit.tgz 2. Say
yes to everything except to do the Update and the firewall,
ports as you wish... 3. vi /etc/cvsupfile 4. change
RELENG_2_2 to RELENG_2_2_6_RELEASE 5. cvsup -L 2 -g
/etc/cvsupfile 6. cd /usr/src 7. make world (do not reboot
afterwards, this takes a long time). 8. backup /etc/ (cd
/etc; tar cvf /tempdir/etcback.tar) 9. cd
/usr/src/sys/i386/conf 10. cp GENERIC MYKERNEL (your kernel)
11. vi MYKERNEL (edit as desired) 12. config MYKERNEL 13. cd
../../compile/MYKERNEL 14. make depend; make; make install
15. cd /usr/obj/etc (not sure on this one, pulling from
memory) 16. rm master.passwd, group, rc.conf (look at this
one and merge where necessary), and whichever other files you
have modified. 17. copy to /etc the rest (with
subdirectories). 18. vi /etc/fstab 19. change wd0a to wd0s1a
20. reboot the beast
