commit: http://git.buildroot.net/buildroot/commit/?id=a118f32e9a72994d46818b8a3374f7905967c52d
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master
This commit does misc improvements to the S80dhcp-server init script:
- Use more variables: NAME, DAEMON, CFG_FILE
- Read the configuration file in /etc/default/ in a more usual way
(as done in S21rngd for example)
- Remove leftover dhcpd3 string in the stopping action.
