Compile FreeBSD Kernel
14:11First of all, you need to have full FreeBSD source tree to build the kernel. If you dont, download them now.
* COPY /usr/src/sys/i386/conf/GENERIC /root/sys/TAO and ln -s /root/sys/TAO /usr/src/sys/i386/conf/TAO
* vi /root/sys/TAO, comment all the device you dont need
* Change scheduler to ULE if you are using FreeBSD 7 (experimental), as mention by Kris, new ULE scheduler has better performance than tranditional 4BSD
http://www.elian.co.uk/2007/12/22/does-freebsd-7-solve-its-mysql-problem/
* Change /etc/make.conf. As V7 support core2 CPUTYPE, so
CPUTYPE?=core2
CFLAGS=-O2 -fno-strict-aliasing -pipe
For pre 7 users, see
http://gentoo-wiki.com/Safe_Cflags#Intel_Core_2_Duo.2FQuad_.2F_Xeon_51xx.2F53xx
*Go to /usr/src/sys/i386/conf directory, and run config TAO to create a compile directory. It is very helpful if you want to keep serveral version of kernel
* Go to ../compile/Tao and run make cleandepend && make depend
* and “make”, it will take very long time and depending on the speed of your machine and your configure file
* make install and reboot your machine. If the new kernel cannot be load correctly or some devices do not function, you can use load kernel.old or kernel.GENERIC to go back to old kernel or generic kernel
N.B. here is my kernel configure file
http://www.elian.co.uk/2007/12/23/taos-kernel/
* After installing new kernel, you have to rebuild your world, otherwise, many program cannot run correctly(To me, sockstat -cl cannot should TCP ports listening)
cd /usr/src
make buildworld (took about two hours)
reboot into single user mode
mergemaster -p
make installworld
mergemaster
reboot

My FreeBSD installation
13:03* Minimal installation(very simply, google it or follow the manual book on FreeBSD website). enable softupdate for non-root slice
* Install man package
* Install cvsup by pkg_add -r cvsup-without-gui (run rehash or re-login)
* Install vim “pkg_add -r vim-lite”
* Using vim instead of vi(may have security issue, careful!). ln -s /usr/local/bin/vim /bin/vi
* Copy /usr/local/share/vim71/vimrc_example.vim to /usr/local/share/vim71/vimrc (gramma hightlight)
* I prefer to use stable-supfile, so copy it to /root and change host address
* Copy /var/share/examples/cvsup/refuse to /var/db/sup. Dont download source code other language, english only.
* Update source code tree now, by cvsup stable-supfile.
* It will take some time, so sit back and have a cup of coffe ^_^
* I personally like to use portsnap to update port tree, so “portsnap fetch extract”
* Copy and edit /etc/make.conf. Change CFLAG and disable GUI by
NO_X= true
NO_GUI= true
WITHOUT_X11= yes
WITHOUT_XPM= yes
* Edit /etc/rc.conf
* To compile kernel, you can follow my another post on
http://www.elian.co.uk/2007/12/23/compile-freebsd-kernel/
* Email system:
I prefer postfix, and you can find many webpage in google on how to replace sendmail with postfix. and it is easy to do so
cd /usr/src/mail/postfix
make install
select SASL2 and TLS, if you need MySQL support, simply add MySQL
add sendmail_enable=”NONE” to /etc/rc.conf
cp /etc/default/periodic.conf /etc/periodic.conf and change following directive (Disable sendmail dail)
daily_clean_hoststat_enable="NO" daily_status_mail_rejects_enable="NO" daily_status_include_submit_mailq="NO" daily_submit_queuerun="NO"
* Config postfix by editing /usr/local/etc/postfix/main.cf
* Install other services

Fedora 7 is released
31/05/2007 20:45Fedora 7 is offically released today. After several warning from friendly blogs, I decided to stay on FC6 until workable solution comes out.
As mentioned, Fedora 7 changed a lot on hardware driver, and the way of modules building into kernel. It is in theory blocked the way upgrade from previous version. From this pointview, Debian is always the best distro of Linux, so easy to upgrade from one version to another!
