Hi, everyone -
Today we uploaded to second of two major changes that will hopefully
improve the Debathena user experience going forward. The first has to
deal with how kernel upgrades and OpenAFS modules are handled, and the
second involves printing.
== OpenAFS Modules ==
If you're using OpenAFS, we've added a series of metapackages that will
stop kernel upgrades until new versions of OpenAFS modules are uploaded.
This will prevent people from getting cryptic errors every once and a
while after they reboot, not realizing that they've taken a kernel upgrade.
To use these new metapackages, download and run our special installer
script:
wget http://debathena.mit.edu/install-openafs-metapackage.sh
sudo sh install-openafs-metapackage.sh
Any future installs of Debathena will automatically use these
metapackages as well.
== Printing ==
As those of you who use Ubuntu know, MIT's LPRng-based printing
architecture doesn't coexist well with CUPS, the architecture used by
default in Ubuntu and GNOME. To make this integration work better, SIPB
is currently running a CUPS server, cups.mit.edu. The newly uploaded
debathena-printing-config package causes the GUI interface to use
cups.mit.edu, which currently serves all cluster and dormitory printers.
It also changes the lpr, lpq, and other associated command line
utilities to intelligently select between CUPS and LPRng.
lpr, lpq, lprm, etc. should all continue to work as you expect them to.
However, if you need to explicitly access a CUPS queue, you should
prepend the command with cups- (i.e. cups-lpr, etc.). If you need to
explicitly use LPRng, prepend mit- (i.e. mit-lpr, mit-lpq, etc.)
As always, feel free to contact the Debathena team at debathena@mit.edu
if you have any questions or issues.
