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.

Description Daniel Riek 2011-06-08 11:06:03 UTC 
When mounting an nfs4 share on a RHEL 6.1 instance with the "context=" option in order to allow a confined service to use it, the option is ignored and the nfs_t context is applied instead of the one set with "context=":

"""
[daniel@swrepo var]$ cat /etc/redhat-release 
Red Hat Enterprise Linux Server release 6.1 (Santiago)

[daniel@swrepo var]$ mount -v | grep ISO
storage000:/swrepo000/ISO on /mnt/ISO type nfs4 (rw,context="system_u:object_r:httpd_sys_content_t:s0",addr=XXX.XXX.XXX.XXX,clientaddr=XXX.XXX.XXX.XXX)

[daniel@swrepo var]$ ls -ldZ /mnt/ISO/
drwxr-xr-x. root root system_u:object_r:nfs_t:s0       /mnt/ISO/
"""

Mount correctly reports the context option, however the actual context set is different.
