Linking s6-linux-init to s6-supervise

Hi,

I have been experimenting with s6* programs for a couple of months and,
by progressively replacing the sysv boot scripts with s6 services, now
have my current system booting and running without sysvinit. Supervised
logging with s6-log is also working, replacing sysklogd.

Despite not really knowing how all this worked, I decided to build a
new version of Linux From Scratch (LFS) without sysvinit and sysklogd,
using s6* instead. S6LFS?

The new build boots, I get a Login prompt and s6-svscan is running as
pid 1 but nothing else happens. None of the 'compiled' services are
copied to the /run directory.

I have clearly missed a step, hopefully a simple one, and the annoying
thing is that I obviously took that step for my current working system
without recognising it!

Any help would be appreciated.

Thanks
