and the aim of OpenWrt is to fit as much as possible in a small image.
My image is still under 8 MB and I take the luxury of including pppoe, freeradius, batman, batctl-full, bird2 and bird2c, wpad-openssl, ... My point: The 4 MB era has already ended, and I still have some space left....
That beside, it might be just an historic reason why odhcpd was chooses back in the days, and I do not doubt that it has its use cases but compared to dnsmasq it seams to have a limited feature set. Only by comparing the wiki, man pages and documentation within each src/git.
That dnsmasq is trying to do/is doing "stuff" far beyond is another discussion, but as a user, I would expect that, if my (dhcp) clients hostname is available on the local dns via v4, and it should be available on v6, too.
And it seams not to work properly on a default installation, again please correct me if I'm wrong!
If this is really the case, that on a default installation a dhcp client is accessible by its name on v4 but not on v6 then this is a bug and not a feature. And I can hardly imagine that nobody encountered this misbehavior before me.
Another note: The wiki is full of esoteric examples I imagine only 0.001% of the user base or even less will ever use, but these examples are there. This is good and this is bad. I'm not in the position to judge why or why not people want to stuff they way they do. But again, if the wiki page of dhcp lists all possible config options even these which are not available on a default installation with the mark that the user is expected to install addition software or swap a packaged, then this fact would be on other options too. Or the mark that that or the other option is used by odhcp AND by dnsmasq(-full). Documentation is only cool when it is complete, because then software can be used by the user.
And last point before I say good night: The last time I checked:
The name LEDE is an abbreviation for Linux Embedded Development Environment, a reference to its flexibility and embedded buildroot origins, making it a solid choice for embedded Linux applications far beyond the wireless router and network appliance realm.
Good night -.-
