Thanks to !158 (merged) , in a slaprunner we can use slapos command:

$ slapos supply https://lab.nexedi.com/nexedi/slapos/raw/1.0.19/software/erp5/software.cfg slaprunner

works fine to supply a software to "current" webrunner, but building this software with slapos node software fails with:

$ slapos node software

because slaprunner's web interface also runs software, it's better both slapos node software command and the one from slaprunner web interface uses the same pid file so that they do not run in parallel.

This depends on slapos.core!29 (merged)
