upgrading RH 9 system->Fedora with iso files and apt only
by Didier Casse
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
apt-cdrom. Thanks.
With kind regards,
Didier.

kernel/accounting question ...
by William W. Austin
(I know that this question might be more reasonable on a kernel list,
but a while back I posted the question twice and got no answers.)
The acct struct is defined in /usr/include/sys/acct.h includes both
ac_io and ac_rw for bytes transferred and blocks read or written,
respectively. Fair and good - works (on paper) similarly to unix,
solaris, hp-ux, etc.
However, in the kernel code [kernel/acct.c], ac_io (char) and ac_rw
(blocks) are always set to 0 by these two lines:
ac.ac_io = encode_comp_t(0 /* current->io_usage */);
ac.ac_rw = encode_comp_t(ac.ac_io / 1024);
For most purposes, this probably wouldn't be an issue, but I also do
extensive performance analysis on several platforms and have written a
fairly compresive accounting package (as a wraparound for psacct or as
a standalone) including both an improved acctcom and a built-in
reporter for it.
Does anyone know wby the kernel zero's out the bytes transferred data?
(Overhead comes to mind.) Not that it makes a huge differnce for my
purposes (I had to write some wraparound code to make a
"best-guestimate" about the data I'm missing), but curiosity is bugging
me now. When I compile my program on other OS's I get useful data for
char and block i/o and I'd like to find out whether there is something
obvious that I'm just totally missing here...).
Thanks

acctcom for linux
by William W. Austin
I recently made several updates to a Linux version of of acctcom
(actually another accounting add-on package) which I've been using for
several years, and one of the people testing it asked a question which
I cannot answer. I'm hoping that someone on this list can give me some
info.
I have previously (over a year ago) asked on both this and a couple of
kernel lists (several times there) about this issue, but nobody has
ever answered. So if you have any info about this, I'd really
appreciate it.
As in many (all?) previous Linux kernels, the struct acct (defined in
/usr/include/sys/acct.h) has members ac_io and ac_rw which are
presumably counts of characters transferred and blocks read/written
respectively.
However, in the kernel code, the ac_io is set to 0 and the ac_rw gets
set to (ac_io/512) or some such - it is set to 0 as well (and thus
these are always reported as 0 in process accounting records. not good
if you're trying to measure them...).
Does anybody know why this is done that way? A long time ago (IIRC
late 2.2 and an early 2.4 kernel) I looked into "fixing" this in the
kernel code but was not successful (I finally produced a bootable
kernel, but it was unstable. Then I changed jobs, got swamped at work,
and eventually gave up).
As I said above, I have previously asked about this issue without
success, and I have essentially given up changing or "fixing" it.
But if anyone knows __WHY__ it is this way (I'm hypothesizing that it's
just too much work for too little added value), I'd really appreciate
knowing the reason. Curiosity and the cat and all that ...
Thanks
- Bill

Packages looking for new owners
by Trond Danielsen
Hi everyone,
it is becoming clear to me that I can no longer provide the collection
of packages I maintain the love and care that they deserve. If only
there were more hours in a day, but the current situation does no
leave much room for volunteer work on free software :-(. Hopefully I
will find time in the future to return to Fedora related work
The list if packages I maintain is available here:
https://admin.fedoraproject.org/pkgdb/users/packages/trondd?acls=owner
I don't mind keeping libopenraw, avrdude and uisp unless anyone
_really_ want to maintain these packages.
Best regards,

Changing the default 32-bit x86 arch for Fedora 12 (#2)
by Bill Nottingham
Given the loud feedback, I've updated the proposal at:
https://fedoraproject.org/wiki/Features/F12X86Support
The revised proposal:
- Build all packages for i686 (this requires cmov)
- Optimize for Atom
Why?
- We don't really support i586 in any meaningful matter
- OLPC still works with base i686
- We are likely doing a mass rebuild for F-12 anyways, might as well switch
while we're doing it
- Atom is the only currently produced 32-bit x86 chip of note; optimize
for what's currently available
If you want numbers, I did some benchmarking of code [1] with various
build options on a variety of processors, with the F-11 gcc code. All
of these results are relative to a F-11 baseline of "-march=i586
-mtune=generic".
P4 2.4Ghz Athlon 3400+ Core2Duo E6850 Atom N270
march=i686/ -1.1% +2.0% +0.9% +0.6%
mtune=generic
march=i586/ +0.3% -0.3% -0.2% +1.3%
mtune=atom
march=i686/ -1.5% +1.2% +0.5% +1.7%
mtune=atom

orphaning nopaste // ruby help wanted for broken package
by Simon Wesp
Dear List,
short version:
I'm going to orphan nopaste since rafb.net/paste, which was used by
this package, is discontinued (bug #504108).
I tried to contact upstream four times and asked if they were planning
to switch to another provider, but no avail
If someone with ruby skills is able to rewrite nopaste for another
pastebin, he/she is welcome to take over the package.
long version:
I'm the maintainer (not a good one) of "nopaste". I was wondering
myself that the pasteservice of rafb.net/paste closed on my birthday.
I contacted the upstream of nopaste on the same day
(25th May), 3 days later, a week later, and yesterday. I wrote him the
situation and my problem (i believe the same problem is in gentoo,
too, because they have nopsate, too[didn't find a solution @ gentoo])
and I hint at the urgency.
Nothing happened. :-(
Yesterday I got the bug #504108. I can't ruby, so I can't fix it. I took
over the review from Phillip Baum, who discarded the idea to
become a Fedora packager.
My most important question is:
Can anybody wrote the script to fpaste.org or an other pastebin, to
continue the life of this package in fedora?
I will hand over the package to the guy(s) who can fix this, of course.
I'm really awfully sorry, for orphaning this package with an open
bug. :-(

Sorry for the noise. I scratched and rebuilt the iPod db on the
iPhone, and then amarok-1.4.10 worked without problems.
If anyone are interested in the packages, they are available from
