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the product is no longer active in Red Hat Bugzilla.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.
docker-common-1.9.1-33.el7 introduces /usr/bin/docker as a wrapper script that selects between docker-current and docker-latest. The exec line currently reads:
exec ${DOCKERBINARY} $@
The $@ is missing double quotes. It should be: "$@" (double-quote, dollar, at, double-quote). See 'Special Parameters' in bash(1) for really-kind-of-inadequate explanation, but basically, without the double-quotes, you lose information about individual params and/or spaces within params.
docker-latest does require docker-common and people could edit /etc/sysconfig/docker to point it to /usr/bin/docker-latest, or do you want this pointing to /usr/bin/docker-latest to be automatic if we only have docker-common and docker-latest installed?
Well docker command will fail if there is nothing set in /etc/sysconfig/docker. Which might be fine, but we should enhance the script to point this out as an error. Or for now make the script look for /usr/bin/docker-common followed by searching for /usr/bin/docker-latest.
We still have an /etc/sysconfig/docker-latest, correct?

Yes
Also, should DOCKERBINARY be set in a new /etc/sysconfig/docker-common instead, or does it suffice to have it in /etc/sysconfig/docker itself (latter means less work for me)
