The native mechanism for the system is the service bundle. However, one can convert and import service configuration from various external formats.
A suite of redo scripts in /etc/system-control/convert/ are supplied for tying these altogether.
Simply executing redo all in that directory will attempt to import from various external configuration formats into service bundles.
Because this mechanism detects changes to source files, it means that it only performs conversion actions when source configuration files have changed.
The redo procedure is best invoked as a post-processing step after running some system utility that has changed an imported system configuration file.
Consider it a step akin to running pwd_mkdb after editing the master.passwd file; running newaliases after editing the Sendmail aliases file; or cap_mkdb after editing termcap entries.
It is wasteful to run it at bootstrap.
