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.

One-line patch to fix this bug

Description of problem:

When writing a custom install class, I attempt to use iutil.execWithCallback to run a chrooted command.  My code failed because execWithCallback never actually makes a chroot call.

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

This issue was present in anaconda in RHEL 6.3 (and many prior versions), and is still present in the master branch.

How reproducible:

Always

Steps to Reproduce:

1. Create a custom install class
2. Define a postAction method
3. Have the method call iutil.execWithCallback with root='/mnt/sysimage'

Actual results:

The method tries to exec without chrooting, often resulting in a buried "Command not found" error.

Expected results:

The command should run chrooted.

RHEL-7 or RHEL-6?  Your patch isn't against rhel6-branch.

patch for RHEL 6 branch

Sorry, here's the RHEL 6 version of the patch.  I forgot that the file path of util.py changed... the patch is otherwise identical across branches.

Comment 6 Samantha N. Bueno 2015-07-17 15:27:59 UTC 
Moving this to 6.8 planning.
Comment 8 Jan Stodola 2016-02-22 13:13:40 UTC 
execWithCallback is chrooted as expected:

-bash-4.1# export PYTHONPATH="/usr/lib/anaconda"
-bash-4.1# ls -l /mnt/sysimage/test
ls: cannot access /mnt/sysimage/test: No such file or directory
-bash-4.1# python                               
Python 2.6.6 (r266:84292, May 22 2015, 08:34:51) 
[GCC 4.4.7 20120313 (Red Hat 4.4.7-15)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import iutil
>>> iutil.execWithCallback('touch', ['/test'], root='/mnt/sysimage')

>>> 
-bash-4.1# ls -l /mnt/sysimage/test
-rw-r--r--. 1 root root 0 Feb 22 08:11 /mnt/sysimage/test

Moving to VERIFIED.
