Hey all,

i`m digging into reinstalling on the latest version (last version I used
was 1.4) I am building from source and seems to have gone ok so far. I have
configured my dhcp4 conf file, but when starting I get this error:

On the first install I noticed the leases file didnt exist so I have just
created a blank file and thought starting the service would populate it but
it seems it needs some content in the file before it can.

Does anyone know what needs to be in the file or have an example? google
searches havnt turned up much so far

Thanks
