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.

Patch to fix

Description of problem:
According to the man page :
 -P     Don't set PATH.  PATH is instead inherited from the environment.
but this does not work, the default path is set : /usr/bin:/bin

Version-Release number of selected component (if applicable):
cronie-1.4.11*

How reproducible:
Easy

Steps to Reproduce:
1. set CRONDARGS="-P" and PATH="/newpath/ in" /etc/sysconfig/crond
2. Add a task with no PATH defined : /etc/cron.d/echopath 
SHELL=/bin/bash
* * * * * root echo $PATH >> /tmp/path_cron
3. restart crond : systemctl restart crond

Actual results:
cat /tmp/path_cron
/usr/bin:/bin


Expected results:
cat /tmp/path_cron
/newpath/

I have a srpm and rpm that fix this issue.
Comment 3 Daphne Shaw 2018-07-24 03:20:41 UTC 
I just hit this bug as well.  Is there some reason why it was closed WONTFIX?  Is there a workaround or a better way to do this?
Comment 5 Chris Williams 2018-11-05 15:25:50 UTC 
This BZ will be evaluated for release in 7.7.
