Yes. This is tricky and didn't have a good idea how to check it. There's
the parameter NET_SNMP_MIB_MODULES which is used in this parameter in
the prepare stage:

  --with-mib-modules=$(PTXCONF_NET_SNMP_MIB_MODULES)

You have to add/include "agentx" in the ptxdist menuconfig entry
NET_SNMP_MIB_MODULES. You can add other and there's no simple switch for
each of them. This is the way to enable several things in net-snmp and
lldpd seems to check it the right way, but I had no idea how to
"translate" this mechanism to the ptxdist layer above.

This is the default lldpd uses. See the output of ./configure from
lldpd:

  --with-privsep-user     Which user to use for privilege separation
                          [default=_lldpd]
  --with-privsep-group    Which group to use for privilege separation
                          [default=_lldpd]
  --with-privsep-chroot   Which directory to use to chroot lldpd
                          [default=/var/run/lldpd]

Actually I set this user to nobody and the group to daemon. As far as I
understood lldpd this is hardcoded and I wanted to have it configurable
so I added it to the ptxdist menu and copied the defaults from lldpd.
Maybe the do not make sense for most of the users. Do you have a better
suggestion for this user and group?

Good to know, but for me the code of the in rule is more clear if I add
this. However, if you want to have it removed, I'll remove it.
