Remove the B flag, that stops it forking to the background.
You may need the ipv6ra_fork option if your RA doesn't provide the RDNSS
option and you're not doing an IPv4 setup to avoid the timeout error.

As you're setting one interface via the flags and not dhcpcd.conf I
would recommend adding the M flag as well in-case you want to use any
dhcpcd tools further down the road.

The resolv.conf part is tricky - because dhcpcd supports DNSSL and RDNSS
options that need to expire it needs to be able to manage resolv.conf
somehow. The solution is to either disable dhcpcd from writing to it at
all (--nohook resolv.conf), setup your static config using
resolvconf.conf or make the file immutable. Is this something we should
document in resolv.conf(5)?
