Me too. Having something which is good enough for most use in base
would be useful.

The rc script name is the main problem for coexistence. Actual daemon
name is ok either way as they are in separate namespaces /usr/sbin
and /usr/local/sbin.

There's another minor one in that systems which already use Vincent
Bernat's lldpd from packages will have an _lldpd user but I don't think
lldpd will need to own any files in base*.tgz/etc.tgz so the actual
numeric value of the uid probably doesn't matter.

Packages lldpd uses /var/run/lldpd.socket and dlg's
/var/run/(o)lldpd.sock so there's no conflict in /var/run filenames.
