Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
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 behavior of mount does not appear to be correctly documented for to "acl" option. It appears the acl option is set by default. Also, there is third party documentation (Michael Jang's book to study for the RHCSA) that documents incorrectly that the "acl" option must be specified. This is not a critical flaw, but it does cause confusion for users studying for the RHCSA. Updating the man page would probably be the easiest resolution.
defaults
Use default options: rw, suid, dev, exec, auto, nouser, async, and relatime.
Version-Release number of selected component (if applicable):
How reproducible:
Very reproducable
Steps to Reproduce:
1. cd /root
2. setfacl -m u:smccarty:r install.log
3. getfacl install.log
Actual results:
# file: install.log
# owner: root
# group: root
user::rw-
user:smccarty:r--
group::r--
mask::r--
other::r--
Expected results:
setfacl -m u:smccarty:r install.log
setfacl: install.log: Operation not supported
or update the man page
Additional info:
Note that 'acl' is not VFS mount option (generic mount option), so it does not make sense to add it to the description for the 'default'.
The 'acl' is filesystem specific and it's enabled pre-filesystem (for example according to info in FS superblock). See for example for extN:
# tune2fs -l /dev/sda4 | grep options
Default mount options: user_xattr acl
I have added a hint about this to the mount.8 man page rathe than hardcode anything about 'acl' there.
Since the problem described in this bug report should be
