Grid Appliance 2.04.07 (beta)

[David Isaac Wolinsky]

To those interested, I've created a new appliance version 2.04.07, here
are some highlights:

- Updated to Ubuntu 10.04 and now we can use their resolvconf again
(this is a LTS release and will probably be the last upgrade we make to
the core appliance for a long time)
- Firewall was preventing jobs from running on the local host (fixed)
- Limit concurrent uploads / downloads to 10, improves responsiveness of
the system -- really need a rate limiter for Condor networking
- Added a new versioning scheme, its available in the startd ads via
APPLIANCE_VERSION, 2.04.07 => 1
- Fixed some issues that were preventing keyboard to set owner and
reclaim a resource
- Enabled periodic updates via apt
- Ubuntu 10.04 doesn't have a proper version of condor_kbdd, so that
needed to be added through our packages :(
- This version includes an IPOP that has a few fixes
-- Local discovery was broken
-- Python daemon should disappear

Anyway, the entire system should work just fine on it, but my
verification has been limited so far. If you're interested in testing
it out, download your flavor from:
http://www.grid-appliance.org/files/appliances/beta/

Note for those that use 9.10, I plan to support both versions, but my
efforts will focus on 10.04.

Also I want to comment on some messages that have been passed around
regarding additional libraries. It would be nice for us to have some
means to include additional code into the system to make users
deployment easier, but there are a few things going against that:
- in the default appliance, we want to keep it slim and not overly get
involved with tailoring it towards any specific environment, so unless
there is a really strong motivation to include something, we probably won't
- in Archer, the idea of including multiple libraries, simulators,
emulators, etc in the VM has been mentioned a few times, but it comes
with the challenge of maintaining potentially an x86 and a amd64
version, ensuring that the user runs the task against the correct one,
and then requiring us to compile versions if they aren't in the package
manager. I'm open to options, but I think one of the core requirements
for inclusion is that it must be horribly complex (i.e. simics) or have
a 64 and 32 bit version in Ubuntu. I am very interested in other
alternatives.

Regards,
David
