-====== Updating Debian packages ======
-A //quick update// can be done by
-  apt-get update
-  apt-get upgrade
-For general installation, updates, and so on <code>aptitude</code> is a good choice.
-===== Caveats =====
-Anything that shouldn't be updated? Like stuff with custom patches?
-Does apt have a history of clobbering configs or anything?
-====== Updating kernels ======
-  apt-get update
-  uname -a                                                                # Figure out which kernel series this machine needs
-  apt-cache search kernel-image | grep somethingwhichidentifiestheseries  # Find the latest kernel in the series
-  apt-get install kernel-image-latestversion-series
-  vim /etc/silo.conf                                                      # Insert information about new kernel
-  silo
-  shutdown -r N
-so for example:
-<code>
-uberjoe@davros:~$ uname -a
-Linux davros 2.6.8-2-sparc64 #1 Fri Jun 10 00:38:40 UTC 2005 sparc64 GNU/Linux
-uberjoe@davros:~$ apt-cache search kernel-image | grep sparc64
-kernel-image-2.6.8-2-sparc64 - Linux kernel binary image for UltraSPARC (sparc64) systems
-kernel-image-2.6.8-3-sparc64 - Linux kernel binary image for UltraSPARC (sparc64) systems
-uberjoe@davros:~$ sudo apt-get install kernel-image-2.6.8-3-sparc64
-boring debian package installation stuff
-uberjoe@davros:~$ sudo vim /etc/silo.conf
-uberjoe@davros:~$ sudo silo
-/etc/silo.conf appears to be valid
-uberjoe@davros:~$ sudo shutdown -r now
-</code>
-The block you need to add to silo.conf should look like:
-<code>
-image=/boot/vmlinuz-2.6.8-3-sparc64
-        Label=debian-normal
-        append="UDEV_DISABLED=yes"
-        initrd=/boot/initrd.img-2.6.8-3-sparc64
-</code>
-Don't remove the old kernel from the file, rename it instead, just in case things go wrong. Also, make sure that the new kernel is set to be the default (default=debian-normal at the top of the file, for example).
-===== Caveats =====
-Anything tied to specific kernel versions?
-The stock Debian stable kernels have a bug in the serial drivers that make the console on Ultra 5s unusable.  We previously fixed this with a slightly later version of the package (2.6.8-16), but it looks like the security update (2.6.8-15sarge1) should have the console fix, along with a bunch of security fixes.  I haven't tested this version yet.
