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 of problem:
The default option specification (i.e. ‘ro’) should be overridden by the host-specific option. That’s how it used to work.

Version-Release number of selected component (if applicable):
RHEL-7.2 with nfs-utils-1.3.0-0.31.el7

How reproducible:
100% easy

Steps to Reproduce:
1. See "Actual results" below.

Actual results:
[root@leira nfs]# cat /etc/exports
/export         -ro,sec=sys,sync        localhost(rw,no_root_squash)
[root@leira nfs]# exportfs -rv
exporting localhost:/export
[root@leira nfs]# mount -t nfs localhost:/export /mnt/nfs
[root@leira nfs]# mkdir /mnt/nfs/gnurr
mkdir: cannot create directory ‘/mnt/nfs/gnurr’: Read-only file system

Note that removing the "sec=sys" above causes the test to succeed.

Expected results:
localhost should have the "rw" right.
