Update FreeBSD

General Information

This guide will walk a user through updating his source to follow FreeBSD’s stable branch. adidas pas cher Please make a full backup of the current system before following this guide.


Requirements

  1. A working install of FreeBSD 5.x (steps may work in other versions)
  2. Root access
  3. Internet access

Installation

Login as root (or login as a user and su to root). Install cvsup and fastest_cvsup with either of the following methods.

 # cd /usr/ports/net/cvsup_without_gui # make install distclean # cd /usr/ports/sysutils/fastest_cvsup # make install distclean 

or

 # pkg_add -r cvsup-without-gui # pkg_add -r fastest_cvsup 

Copy the sample supfile for Stable to the root directory

 # cp /usr/share/examples/cvsup/stable-supfile /root 

Run cvsup to download the latest stable source using the fastest cvsup server near you.

 # cvsup -L 2 -h `(fastest_cvsup -q -c us )` /root/stable-supfile 

When the cvsup has completed, change to the /usr/src directory

 # cd /usr/src 

Now take the time to read /usr/src/UPDATING. ugg bailey button This file will contain information that may be needed to properly update the FreeBSD source.

Now it is time to compile this source. ugg bottes chaussures timberland soldes This is called building world.

 # make -j4 buildworld 

Note: The -j4 switch is used to spawn multiple processes and according the FreeBSD Handbook, testing shows that this speeds up building world even on a single CPU system. nike air max 2016

Now build a new kernel. To rebuild the GENERIC kernel, simply run the following command:[/code]

 # make buildkernel 

To build a new kernel using a custom kernel configuration file, run the command as follows:

 # make buildkernel KERNCONF=MYKERNEL 

Note: To create a custom configuration file, go to /usr/src/sys/i386/conf and make a copy of the GENERIC file; name it something like MYKERNEL. adidas pas cher Editing the kernel configuration file is beyond the scope of this walk-through. ffxiv gold new balance soldes

Now boot to single-user mode. bns gold bottes ugg pas cher This is important because replacing system files while in use in a running system is not a good idea.

Note: Installing the kernel and world in single-user mode is not required. It is only the safest method. If you wish, you can do the entire process from multi-user mode. asics gel lyte iii ugg olsen
 # shutdown now 

Once in single-user mode, run the following commands to get access to the file system and the swap.

 # fsck -p # mount -u / # mount -a -t ufs # swapon -a 

Change to the /usr/src directory.

 # cd /usr/src 

Now install the new kernel. To install the rebuilt GENERIC kernel, simply run the following command:

 # make installkernel 

To install a newly built custom kernel, run the command as follows:

 # make installkernel KERNCONF=MYKERNEL 

Reboot

 # reboot 

On boot up, select option 4 to boot to single-user mode. bottes ugg pour homme Once in single-user mode, run the following commands to get access to the file system and the swap.

 # fsck -p # mount -u / # mount -a -t ufs # swapon -a 

Change to the [code]/usr/src directory.

 # cd /usr/src 

Run mergemaster -p to compare only those files that are essential for the success of buildworld or installworld.

 # mergemaster -p 

Select No to when prompted to remove /var/tmp/temproot. new balance running Now install the new world.

 # make installworld 

Now run mergemaster to compare all the configuration files.

 # mergemaster 

Note: Unfortunately the mergemaster is the most complex and the least amount of help is provided. Understanding how mergemaster works will help. ffxiv gold nike air max 90 femme It compares the configuration files in use on the current system with the new configuration files from the newly compiles source. bns gold It uses diff to display both files at the same time. nike dunk Lines that are new and will be added if the new configuration file is installed have a plus (+) sign by them. ugg pour homme pas cher Lines that will be removed from the configuration file if you install the new one have a minus (-) sign by them. ugg australia bailey button One tip is that if the changes are only to comment lines (comment lines begin with a pound (#) sign) it is usually safe to install the new configuration file. ugg men timberland earthkeepers bottes Another tip is that if there is a minus (-) sign next to something that needs to be kept, do not install the new file but either leave the file to be dealt with manually or merge the two files. new balance pas cher asics kinsei
Note: It is common to run mergemaster multiple times. chaussure adidas adidas pas cher

Reboot the system.

 # reboot 

Once the reboot has completed, the system should boot the stable release. ugg boots bailey bow timberland roll top pas cher Adidas Running Login and verify that everything is working correctly.

Note: It is a good idea to update the ports tree after rebuilding from source. new balance 2017 bottes ugg australia pas cher See the following guide for updating the ports tree.
