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.

Expected results:
no traceback

Additional info:
Comment 1 James Antill 2011-06-08 14:16:56 UTC 
Do you have the "local" plugin installed?
Comment 2 Petr Sklenar 2011-06-09 06:56:14 UTC 
Comment 0 was without local plugin and actually I cannot reproduce it now (maybe more package were updated , ... will try later)

And with yum-plugin-local-1.1.30-6.el6.noarch there is longer traceback and mainly yum stops to continue. Its reproducible with each new package installed and in working nfs directory which is deleted.

Comment 4 James Antill 2011-12-20 19:36:21 UTC 
Not 100% a yum bug, but it seems easiest to work around it in yum with the open(".") fix.
Comment 6 Zdeněk Pavlas 2012-02-14 14:58:44 UTC 
Merged the upstream fix, resolves Bug 698795 as well.
Comment 8 Karel Srot 2012-04-05 11:47:08 UTC 
This fix has a side-effect which let's me install package from / directory when running localinstall from removed directory.

I though I could use that to redirect yum to use /etc/yum.conf instead of differen etc/yum.conf passed using relative address... 

But yum crashes in that case:

# rpm -q yum
yum-3.2.29-28.el6.noarch
# mkdir p
# cd p
# rm -rf ~/p
# yum -c etc/yum.conf install zsh

Yeh, I would just ignore that as a known issue ... along with other things like using --downloadonly and --downloaddir ... I can't see how you could attack a sysadmin this way that wouldn't mean you could attack them just as easily another way.
