Hello Thibor (and others), First of all, nice job on static DHCP. 1) After the static DHCP changes for this version, I'm wondering if there's a way to get rid of *all* old variables from NVRAM that are not being used by the current version of the firmware. For example, I still had static_lease[1-5] in there which I unset manually. Resetting to factory defaults doesn't get rid of them. Is there another way to remove variables that don't apply to the current firmware or what is the proper way to apply a firmware upgrade so that the old NVRAM variables are completely gone? I know it's not a big deal to have 5 extra variables in there that are not being used, but switching between various firmwares and versions may create some garbage which will pile up. 2) Also, would it be possible to remove the requirement to type static_lease in front of each lease? I assume the code could just add it for each line ... Unless that form is intended to enter other options for udhcpd too, in which case it's fine to leave it in there, but a hint line would help. Thanks.
