-====== 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?
-====== cron-apt ======
-We run //cron-apt// to give us warnings via root's email when packages need to be updated.  This should be installed on every box.  Here's the change you need to make to the configuration:

-====== 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
-  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 shutdown -r now
-</code>
-Silo should be set up to load the new kernel magically. If not, some haxing may be required to get the new kernel to work. It's probably best to try and set it up like so:
-<code>
-root=/dev/hda2
-partition=1
-default=debian
-read-only
-timeout=100
-image=/boot/vmlinuz
-        label=debian
-        append="UDEV_DISABLED=yes"
-        initrd=/boot/initrd.img
-image=/boot/vmlinuz
-        label=Linux
-        append="UDEV_DISABLED=yes"
-        initrd=/boot/initrd.img
-image=/boot/vmlinuz.old
-        label=LinuxOLD
-        append="UDEV_DISABLED=yes"
-        initrd=/boot/initrd.img.old
-</code>
-This is more or less how debian has it set up by default, but with devfs turned off, because we don't need it. You might want to check which drive root is on. Debian should update the symlinks in /boot automagically, and all should be well.
-===== 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.
