What problems did you encounter? inet6 autoconf or rtsol in hostname.if are supposed to work exactly the same. > Finally figured out that rtsol is dropped and that the functionality > is moved to the kernel.

When I moved the SLAAC logic into the kernel the main motivation was to get rid of rtsol(8). Back then I suggested to change /etc/netstart and the installer to deprecate the rtsol keyword as well but I got some objections to that. Maybe we should revisit that. Note however that rtsol in hostname.if is a keyword, it does not refer to the (old) /sbin/rtsol binary and never did; exactly the same as the dhcp keyword - there isn't even a dhcp binary. So when /etc/netstart encounters the rtsol keyword it executes ifconfig $if inet6 autoconf. The same for dhcp, it executes dhclient $if. inet6 autoconf in hostname.if works, too, because it's passed to ifconfig by /etc/netstart. I notice an inconsistency however. I recently changed some kernel bits so that SLAAC works with net.inet6.ip6.forwarding enabled. This is needed for RFC 7084 and intended for cpe devices. While inet6 autoconf works perfectly fine with net.inet6.ip6.forwarding enabled /etc/netstart will complain if it encounters the rtsol keyword with forwarding enabled. > > Index: hostname.if.5 > =================================================================== > RCS file: /cvs/src/share/man/man5/hostname.if.5,v > retrieving revision 1.62 > diff -u -p -r1.62 hostname.if.5 > --- hostname.if.5 12 Jul 2014 16:59:06 -0000 1.62 > +++ hostname.if.5 5 Jun 2015 13:30:46 -0000 > @@ -248,26 +248,24 @@ Valid options for a particular interface > .Pp > IPv6 stateless address autoconfiguration: > .Bd -ragged -offset indent > -.Li rtsol > +.Li inet6 autoconf > .Va options > .Ed > .Pp > The above format has the following field values: > .Bl -tag -width indent -offset indent > -.It Li rtsol > +.It Li autoconf > The literal string > -.Dq rtsol > +.Dq autoconf > if the interface is to be configured using > IPv6 stateless address autoconfiguration. > This should be used on single interface hosts only, > since the IPv6 specifications are silent about the > behavior on multi-interface hosts. > Also note that the kernel must be configured as a host (i.e. non-router). > -Add the following line into > -.Xr sysctl.conf 5 : > -.Bd -literal -offset indent > -net.inet6.ip6.forwarding=0 > -.Ed > +This is the default.
