Description Flags
give highest priority to the settings in /etc/sysctl.conf none

Description Andrew J. Schorr 2013-10-10 01:10:29 UTC 
Description of problem: After the most recent patch to systemd, the settings in /etc/sysctl.conf have the lowest priority.  Thus, they are overwritten by the default values in the sysctl.d files.


Version-Release number of selected component (if applicable): systemd-204-16.fc19.x86_64



How reproducible: Boot the system with a setting in /etc/sysctl.conf that conflicts with a default setting.  For example, I have on my system:

bash-4.2$ grep rp_filter /etc/sysctl.conf
net.ipv4.conf.default.rp_filter = 0
bash-4.2$ grep rp_filter /usr/lib/sysctl.d/50-default.conf 
net.ipv4.conf.default.rp_filter = 1

The boot messages include:
Oct 09 11:48:33 ti5 systemd-sysctl[1250]: Overwriting earlier assignment of net/ipv4/conf/default/rp_filter in file '/usr/lib/sysctl.d/50-default.conf'.





Steps to Reproduce:
1. Install /etc/sysctl.conf with values intended to override the default values in the sysctl.d files
2. Reboot
3. Observe that /etc/sysctl.conf has lowest priority

Actual results: Conflicting settings in /etc/sysctl.conf are ignored.


Expected results: The values in /etc/sysctl.conf should have priority.  That was the case until the most recent patch.
