Arch Linux

Description:
For years the /etc/sysctl.conf file has stored non-default settings for entries under /proc/sys so that the corresponding /proc/sys entries are automatically updated when the system reboots.

Sysfs lacks an easy way to store persistent settings in a simple configuration file. In the past, a hacked rc.local file with a series of "echo X > /sys/xxx/yyy/zzz" was used to override default sysfs settings. In addition to being rather ugly, the rc.local service is now at best a second-class citizen with the adoption of systemd in Arch.

Arch linux should adopt a /etc/sysfs.conf setup that enables saving persistent settings under /sys in the same manner as the already familiar /etc/sysctl.conf file does for /proc/sys. This could be expanded to include a directory structure such as /etc/sysfs.d that includes individual config files in a similar manner to /etc/sysctl.d.
