RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Fixed In Version: rpm-4.8.0-20.el6
Doc Type: Bug Fix
Doc Text:
Packages for Fedora >= 17 require a special rpmlib() dependency provided by rpm to track the /usr merge (http://fedoraproject.org/wiki/Features/UsrMove) being done in that version, otherwise it wont be possible to use eg. mock chroot to install and build packages for that distribution. This special tracking dependency has been added to rpm now to allow Red Hat Enterprise Linux 6 to be used as a host for building packages for these newer Fedora versions.

patch for rpm to provide checks for the usr move

To enable the /usr move
https://fedoraproject.org/wiki/Features/UsrMove
we need the attached patch in rpm.
This helps to guard against updating converted F17 packages on an unconverted system.
Comment 2 Panu Matilainen 2011-12-15 09:27:11 UTC 
CondNak on per-need basis - RHEL itself doesn't need this patch, this is only needed for the koji builders and there are three possibilities:

a) builders avoid the need for this by using a special version of filesystem package
a) builders use their own version of rpm with this patch applied (if a is not chosen this will be required temporarily anyway)
c) this patch gets applied to RHEL itself to eventually eliminate the need for a special version of rpm on the builders
Comment 3 Dennis Gilmore 2012-01-18 14:12:10 UTC 
From a fedora releng position I do not want to patch rpm on the builders at all. Please make it work without the need to. yes there has been cases in the past where we have done so. but it makes it really hard for people outside of Fedora to use rhel to build fedora rpms. which a lot of people do. its not a sustainable practice. especially since its a temporary measure its even better to avoid. since its likely to get forgotten in the future. patching rpm also makes life harder for secondary arches. and other consumers of rebuilding our sources.

Not sure, if that's really possible. Fedora 17 will not install any of the
converted packages on a system without the new RPM, or an unconverted
filessystem. That will obviously also applies to the builders.

Unless the builder always use --nodeps to install filesystem.rpm, or some other
trick, we need RPM in the builder provide the functionality needed by the
packages.

I don't have any idea for 'make it work without the need", and we need a
solution this week.

Any better idea?

Thanks!
Comment 5 Harald Hoyer 2012-01-20 16:17:16 UTC 
ok, so Dennis does not want a fork for the Fedora build system.

Panu, we need this in RHEL-6.3!
Comment 6 Panu Matilainen 2012-01-23 12:50:08 UTC 
While I'm not exactly eager to add Fedora-specific patches to RHEL (it wont be "temporary" at that point since we'll be forced to carry it for years to come) I guess I can live with that.

However adding it to RHEL-6.3 wont make it available on builders NOW.
