NAME¶invoke-run - runscript interpreter
DESCRIPTION¶The runit supervision system uses scripts, called runscripts to start services. By convention, runscript for a service foo is located at /etc/sv/foo/run
Debhelper addon dh_runit installs runscript according this convention.
Runscript can be any executable file. Runscript can use invoke-run interpreter only if it is installed according convention,
To use invoke-run interpreter, runscript /etc/sv/foo/run for service foo must begin with following line:
If init.d script /etc/init.d/foo exists, it is invoked with stop argument to gracefully handle package upgrade to version, introducing runscript. After that, /bin/sh shell interpret rest of runscript, with some additional environment set according following rules:
- If file /etc/default/foo exists, it is interpreted with /bin/sh and all variable assignment are accessible to runscript.
- If directory /etc/sv/foo/conf exists, variables are set according to rules, documented in envdir section of chpst(8) manual.
If both /etc/default/foo file and /etc/sv/foo/conf directory define some variable, value from directory takes precedence.
