Red Hat Bugzilla – Bug 1490940
[RFE] make the installer to use sysctl.d directorys instead of sysctl.conf file.

> 3. What is the nature and description of the request? Currently OpenShift ansible installer adds sysctl settings to sysctl.conf, e.g. net.ipv4.ip_forward=1 While sysctl.d directories feel like a better fit for these customizations. > 4. Why does the customer need this? (List the business requirements here) This breaks our puppet modules and also makes hard to trace the changes introduced by OpenShift. Besides the sysctl.conf file provided by RHEL7.3 says: # sysctl settings are defined through files in # /usr/lib/sysctl.d/, /run/sysctl.d/, and /etc/sysctl.d/. # # Vendors settings live in /usr/lib/sysctl.d/. # To override a whole file, create a new file with the same in # /etc/sysctl.d/ and put new settings there. To override # only specific settings, add a file with a lexically later # name in /etc/sysctl.d/ and put new settings there. # # For more information, see sysctl.conf(5) and sysctl.d(5). > 5. How would the customer like to achieve this? (List the functional requirements here) Sysctl settings to be placed under one of the above mentioned directories. > 6. For each functional requirement listed, specify how Red Hat and the customer can test to confirm the requirement is successfully implemented. Will find net.ipv4.ip_forward=1 under /usr/lib/sysctl.d/ with a meaningful filename. > 10. List any affected packages or components. openshift-ansible
This change is in openshift-ansible-3.7.7-1
Verified in openshift-ansible-3.7.9-1.git.0.60e60a0.el7.noarch.rpm /etc/sysctl.d/99-openshift.conf is created and `net.ipv4.ip_forward` is set to 1. # cat /etc/sysctl.d/99-openshift.conf net.ipv4.ip_forward=1 # /sbin/sysctl --system <--snip--> * Applying /etc/sysctl.d/99-openshift.conf ... net.ipv4.ip_forward = 1 * Applying /etc/sysctl.d/99-sysctl.conf ... * Applying /etc/sysctl.conf ... The custom config in /etc/sysct.conf which would override /etc/sysctl.d/99-openshift.conf is applied in the end. This should be expected and correct. Moving to verified.
