Reason for Outage:
Final migration step for new cvs server. It will hopefully be offline for
only 30-45 minutes. The additional time is for some further tuning if
needed and some verification steps.

I have the yarrow's iso files on my HD in a RH9 system. Let's say I want
to upgrade selected packages using an "apt-get install" pointing to my
iso-mounted files, how do I do it?
i.e I mount the iso into some /mnt/yarrow1, /mnt/yarrow 2 etc..
Then what is the complete procedure to make my apt look into my own HD to
upgrade packages. Can anybody redirect me to the correct
resource or some literature hanging on the web? Thanks.
Assume also that I do not wish to burn CDs! I do not want to use

I have been working for a few years (with Fabio Checconi) on a disk
scheduler providing definitely lower latencies than cfq, as well as a
higher throughput with most of the test workloads we used (or the same
throughput as cfq with the other workloads). We named this scheduler
bfq (budget fair queueing). I hope this is the right list for announcing
One of the things we measured in our tests is the cold-cache execution
time of a command as, e.g., "bash -c exit", "xterm /bin/true" or
"konsole -e /bin/true", while the disk was also accessed by different
combinations of sequential, or random, readers and/or
writers. Depending on which of these background workloads was used,
these execution times were five to nine times lower with bfq under
2.6.32. Under 2.6.35 they were instead from six to fourteen times
lower. The highest price paid for these lower latencies was a 20% loss
of aggregated disk throughput for konsole in case of background
workloads made only of sequential requests (due to the fact that bfq
of course privileges, more than cfq, the seeky IO needed to load
konsole and its dependencies). In contrast, with shorter commands, as
bash or xterm, bfq also provided up to 30% higher aggregated
We saw from 15% to 30% higher aggregated throughput also in our
only-aggregated-throughput tests. You can find in  all the details
on our tests and on other nice features of bfq, such as the fact that
it perfectly distributes the disk throughput as desired, independently
of disk physical parameters like, e.g., ZBR. in  you can also find
a detailed description of bfq and a short report on the maturity level
of the code (TODO list), plus all the scripts used for the tests.
The results I mentioned so far have been achieved with the last
version of bfq, released about two months ago as patchsets for 2.6.33
or 2.6.34. From a few days a patchset for 2.6.35 is available too, as
well as a backport to 2.6.32. The latter has been prepared by Mauro
Andreolini, who also helped me a lot with debugging. All these patches
can be found here . Mauro also built a binary kernel package for
current lucid, and hosted it into a PPA, which can be found here .
A few days after being released, this version of bfq has been
introduced as the default disk scheduler in the Zen Kernel. It has
been adopted as the default disk scheduler in Gentoo Linux too. I
also recorded downloads from users with other distributions, as, e.g.,
Ubuntu and ArchLinux. As of now we received only positive feedbacks
from the users.

Sure. Attached. The bugs were mainly with zsh conventions and getting
the sed command for the branch selection corrected.
we use mock for local package build, but it's very slow. now we install
a new host just for mock with 8core, ram disks etc. it seems it still
slow. first of all most of the time mock use only one 1 core of the cpu.
is there any way to speed up different part of the mock build process?
thanks in advance.
ps. anyway is there any better place to discuss it?

I'm currently in process of automatic enlisting of all ~10K Fedora Git
repos at Ohloh. Right now roughly 7% of repositories were added and
overall process will be finished in a 20-30 hours (it takes me about
5-10 seconds to properly add repository, and I don't want to speedup
this process - to prevent Ohloh from accidental DoS).
With best regards, Peter Lemenkov.
I attempted to build a new version of Gimp 2.7.1 using Koji scratch method but
ended up with that result. Here is attached spec file borrowed from Nils as I
wanted to experiment that version along with Design. Can anyone check what went
If someone implement
into the mozilla source, we can easily remove source for the
libraries. And Fedora will be happy. :-)
