vicki: upgrade from Debian 6.0 "Squeeze" to ...

At the time of this writing, vicki is running Debian 6.0.7 "Squeeze":

$ hostname && lsb_release -d && uname -m && date --rfc-3339=seconds
vicki
Description:    Debian GNU/Linux 6.0.7 (squeeze)
x86_64
2013-05-05 09:22:50-07:00
$ 

Support, most notably security support, for Debian 6.0 "Squeeze", will end around or before 2014-05-03, as Debian 7.0 "Wheezy" was released 2013-05-04. It is therefore important to upgrade vicki on or before that date, and preferably sufficiently well in advance, e.g. around roughly 2013-11-04.

vicki is the physical host, which has as Virtual Machine (VM) "guests", both an SF-LUG (sf-lug.org & sf-lug.com) and BALUG VM. Note that since both are on VMs (within qemu-kvm on x86_64), any needed upgrades within those VMs themselves can, for the most part, be handled exceedingly independently. E.g. they can even run quite different operating systems (OSes) - essentially anything that can reasonably be run on the vicki host provided VM infrastructure. The only particular dependencies are resources from and availability of vicki (e.g. the guest VMs obviously can't be running on vicki while vicki is down or rebooting or its VM infrastructure isn't available). Therefore, due to the significant degree of general independence and flexibility, matters regarding those "guest" OSes shall be considered (and documented, as desired and feasible) separately.
