The freebsd-update(8) utility supports binary upgrades of i386 and amd64 systems running earlier FreeBSD releases. Systems running 7.[01234]-RELEASE, 8.[01]-RELEASE, 8.2-BETA1, or 8.2-RC[123] can upgrade as follows: # freebsd-update upgrade -r 8.2-RELEASE
During this process, FreeBSD Update may ask the user to help by merging some configuration files or by confirming that the automatically performed merging was done correctly. # freebsd-update install
The system must be rebooted with the newly installed kernel before continuing. # shutdown -r now
After rebooting, freebsd-update needs to be run again to install the new userland components: # freebsd-update install
At this point, users of systems being upgraded from FreeBSD 7.4-RELEASE or earlier will be prompted by freebsd-update to rebuild all third-party applications (e.g., ports installed from the ports tree) due to updates in system libraries.
8. Back up any files in /usr/local you wish to save,
such as configuration files in /usr/local/etc
9. Manually check /usr/local and /var/db/pkg
to make sure that they are really empty
10. Re-install portmaster
11. portmaster `cat ~/installed-port-list`
After updating installed third-party applications (and again, only if freebsd-update printed a message indicating that this was necessary), run freebsd-update again so that it can delete the old (no longer used) system libraries: # freebsd-update install
Finally, reboot into 8.2-RELEASE: # shutdown -r now
ssh-keygen generates, manages and converts authentication keys for ssh(1). ssh-keygen can create RSA keys for use by SSH protocol version 1 and RSA or DSA keys for use by SSH protocol version 2. The type of key to be generated is specified with the -t option. If invoked without any arguments, ssh-keygen will generate an RSA key for use in SSH protocol 2 connections.
