HowTo: Upgrade FreeBSD 7.2 to 7.3

Disclaimer: this post is for those that instead of using FreeBSD's excellent documentation maintain the bad habit of googling for things already covered in the project's official documentation. This is more or less a copy-paste of the FreeBSD 7.3-RELEASE Announcement instructions for upgrading 7.2 to 7.3.

These are needed steps to upgrade, through the binary upgrade method, the kernel and userland utilities to 7.3-RELEASE:
  1. % su
  2. # freebsd-update upgrade -r 7.3-RELEASE
  3. # freebsd-update install
  4. # shutdown -r now
  5. % su
  6. # freebsd-update install
  7. # shutdown -r now
On step 1 we've started of by becoming the superuser. Step 2 initiates the freebsd-update utility pointing the upgrade to 7.3-RELEASE, after that we proceed with the installation of the kernel on step 3.

Upon rebooting the new kernel is enabled and we move into step 6. Here we end the upgrade process by updating the userland utilities.

That's it!

If you found this post useful that's actually a bad news: you aren't reading the project's official documentation! So please point to and educate yourself on FreeBSD ;)

Tip: Dealing with virtualbox-ose PUEL license on Gentoo

I came across a peculiar message from portage when trying to install virtualbox-ose in Gentoo:
  1. $ su
  2. # eix-sync
  3. # emerge --tree --ask --verbose virtualbox-ose
These are the packages that would be merged, in reverse order:

Calculating dependencies... done!

!!! All ebuilds that could satisfy "~app-emulation/virtualbox-ose-additions-3.1.4" have been masked.
!!! One of the following masked packages is required to complete your request:
- app-emulation/virtualbox-ose-additions-3.1.4 (masked by: PUEL license(s))
A copy of the 'PUEL' license is located at '/usr/portage/licenses/PUEL'.

(dependency required by "app-emulation/virtualbox-ose-3.1.4" [ebuild])
(dependency required by "virtualbox-ose" [argument])

For more information, see the MASKED PACKAGES section in the emerge
man page or refer to the Gentoo Handbook.
The solution is to add the PUEL license to the /etc/portage/package.license file:
  1. # echo "app-emulation/virtualbox-ose-additions PUEL" >> /etc/portage/package.license
  2. # echo "app-emulation/virtualbox-ose PUEL" >> /etc/portage/package.license
Now can finally get to emerge VirtualBox.

As a side note you can also use /etc/make.conf and make use of the ACCEPT_LICENSE variable. For instances adding ACCEPT_LICENSE="*" to /etc/make.conf unmasks all licenses. Alternatively you can unmask licenses one by one.

More information can be obtained reading make.conf and portage's man pages.
