Hi Thijs, Sorry for the late reply.

When you ‘herd load root’ the file above, ‘shepherd’ (PID 1) ends up loading the (guix gexp) and (gnu packages ssh) modules from Guix; it’s halfway turning your init system into a package manager. :-) However… > I get errors (after loading) like: >> Loading > > /mnt/data/engagement/networking/Ouroboros/tools/ouroboros/.guix/modules/ouroboros/testd.scm. >> herd: error: exception caught while executing 'load' on service 'root': >> no code for module (gcrypt hash) … some modules needed by those Guix modules are not visible in ‘GUILE_LOAD_PATH’ for ‘shepherd’. In this case, the (gcrypt hash) module from Guile-Gcrypt, which Guix depends on, is not visible, so loading (guix gexp) fails. There’s another issue: even if ‘shepherd’ managed to load all these modules (which would be possible by adjusting its ‘GUILE_LOAD_PATH’ and ‘GUILE_LOAD_COMPILED_PATH’ environment variables), the ‘make-forkexec-constructor’ expects a list of strings as its first argument, but (file-append openssh …) does *not* return a string—it returns a <file-append> record, and that leads to a type error. HTH! Ludo’.
