I pressed "save & apply" in the "dhcp and dns" settings in Luci without making changes.
Now 4 options in /etc/config/dhcp are missing:
option boguspriv '1' option filterwin2k '0' option nonegcache '0' option nonwildcard '1'
For example "nonegcache" is unchecked in Luci, when I check and save, than
option nonegcache '1'
is written to the config file.
So I think this is correct and "option nonegcache" is set to "false" "in the background", but I don't know if this is a normal behaviour or not?
Thanks in advice, gueni
