Description Bastien Nocera 2005-07-19 05:28:17 EDT
# rpm -qf /etc/readahead.files
# rpm -qf /usr/lib/libz.so.
# grep libz /etc/readahead.files

Arjan mentions that listing a symlink would be fine. Should this be done as part
of the releng tests?
Comment 1 Bastien Nocera 2005-07-19 05:48:34 EDT
Should note this also applies to /etc/readahead.early.files
Comment 2 Dave Jones 2005-10-19 15:57:37 EDT
This is going to be perpetually out of date for one reason or another.
The thing is it needs updating every single time we push an errata, not just
when we do another U release.

And just adding every possible combination would grow the filelist so large that
we'd waste quite a bit of time opening files that don't exist.

Add to this the fun combination that some users mix-n-match bits from different
U releases, and the whole situation is pretty awful.

For RHEL5 there's some discussion about making this list dynamically generated
using the audit mechanism.
Comment 3 Bastien Nocera 2005-10-20 05:22:07 EDT
Dave, we don't change minor versions of the libraries in updates, only micro
versions. Having a symlink listed in the readahead.files will do the right thing
and read ahead the file pointed to by the symlink, so saying that every U would
need an upgrade is false.
Comment 4 Dave Jones 2005-10-20 17:31:07 EDT
ah, I'd misinterpreted this report, and thought that we had
/usr/lib/libz.so. in the GA release.   I see now that wasn't the case.

yes, changing this to a symlink makes sense.
Comment 6 Dave Jones 2005-10-25 17:12:24 EDT
fixed in cvs
Comment 8 Jay Turner 2006-02-03 09:03:44 EST
Fix confirmed with kernel-utils-2.4-13.1.80.  /etc/readahead.early.files now has
the "/usr/lib/libz.so.1" symlink listed instead of an explicit pointed to the
library itself.
Comment 10 Red Hat Bugzilla 2006-03-07 13:05:42 EST
An advisory has been issued which should help the problem
described in this bug report. This report is therefore being
closed with a resolution of ERRATA. For more information

please follow the link below. You may reopen this bug report
if the solution does not work for you.

Comment 12 Bastien Nocera 2006-03-28 10:31:14 EST
$ rpm -qf /etc/readahead.files
$ grep libz /etc/readahead.*

Still broken for the /etc/readahead.files file
