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.

+++ This bug was initially created as a clone of Bug #2049414 +++
Description of problem:
Currently, mounting a filesystem by the device's label fails if there's a space between "-L" and the label. For example, `device="-L IPXE"`. This is because we double-quote the DEVICE variable, which prevents word splitting, when we use it in the mount command.
We can't remove the double quoting, because it was the fix for BZ 1624591, which enabled us to mount devices that **actually** have whitespace in their names.
So I think we have two options:
1. Add a flag (e.g., `uselabel=true`, with default value set to false) that tells the Filesystem resource agent to treat the `device` option as a device label instead of a device name. Then use `$MOUNT -L "$DEVICE"` instead of `$MOUNT "$DEVICE"` if uselabel=true. I favor this option.
2. Do nothing and simply instruct users to omit the space after the -L. So in our example, it would be `device="-LIPXE"` instead of `device="-L IPXE"`. I think this will work but it's a bit counterintuitive and harder to read.
