Is there a trick to re installing the s6 programs or have I just made an obvious mistake?
Generally speaking, --enable-absolute-paths is a bad idea, except in very specific situations. Things will likely work better without that option; I suggest you rebuild the packages again without it. The step you're missing is probably running s6-linux-init-maker again, after rebuilding/reinstalling the packages. Be aware that the default PATH set by s6-linux-init-maker is /usr/bin:/bin, and that's what all the services will inherit. If you have a service that needs a binary in /usr/sbin, make sure to update the PATH in the run script for the service. Alternatively, if your whole infrastructure relies on binaries in /usr/sbin, you might find it easier to adjust the default PATH for the supervision tree, via the -p option to s6-linux-init-maker. HTH, and good luck, -- Laurent
