[systemd-devel] [PATCH v3 2/2] Remove sysv parser from service.c

Thomas H.P. Andersen phomes at gmail.com
Fri May 30 06:28:42 PDT 2014


From: Thomas Hindoe Paaboel Andersen <phomes at gmail.com>

Parsing sysv files was moved to the sysv-generator in the previous commit.
This patch removes the sysv parsing from serivce.c.

To avoid introducing an extra compat option in .service fies for identifying
sysv services we instead add a check if the SourcePath is a path to sysvinit.

Note that this patch drops the following now unused sysv-specific info
from service dump:
"SysV Init Script has LSB Header: (yes/no)"
"SysVEnabled: (yes/no)"
"SysVRunLevels: (levels)"
