Subject: dhcp: adjust initscripts and misc details
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=dcefce4cf81f8a4ca8a5baadc51554e5fb3346a8;p=buildroot.git

dhcp: adjust initscripts and misc details

Revamp initscripts see bug #3601
* Trim whitespace
* Check for installed binary (dhcp-relay)
* Check for installed config (dhcp-server)
* Check for proper variable setup from the script (both)
* Add "FAIL" message when startup fails (blind OK isn't accurate)
* Add start/stop messages to dhcp-relay

Switch bool to "dhcp (ISC)" to keep in line with package sorting.
