system-ml

The system-ml program

system-ml automatically creates logging service source directories for longrun services in the system configuration directory. To create the logging service source directories, system-ml uses longrun-make internally.

Interface

     system-ml

system-ml takes no arguments.
It deletes the src/generated-logger subdirectory of the system configuration directory.
It scans the src subdirecotry of the system configuration directory for longrun services.
It checks for each longrun it detects, whether its source directory contains a file no-ml. If this file exits, this longrun is skipped in the subsequent logger generation.
It generates a logging service source directory at src/generated-logger/@longrun@-log in the system configuration directory. It does so in parallel for each longrun @longrun@-srv it found.

Since system-ml is an execline script, it exits with an approximation of employed program that failed.
system-ml mostly uses execline and s6 software, the exit behaviour of which can be looked up on their respective pages.
See also: execline exit code handling.

The logger services created by this script will drop privileges to @loguser@, which must exist at runtime. (see log directory).
