NAME¶

cpsv - utility to install and manage runit services

SYNOPSIS¶

cpsv  [-f] a <service-name> ...
cpsv  p <service-name>
cpsv  d <service-name>
cpsv  [-f] s
cpsv  l

DESCRIPTION¶

cpsv is a tool to install runscripts from CPSV_SOURCE to CPSV_DEST. It can also be used to manage runscripts that are already installed in CPSV_DEST.
By default in a Debian system, CPSV_SOURCE is /usr/share/runit/sv and CPSV_DEST is /etc/sv.
Usually packages install runscripts directly in /etc/sv/ but it's also possible to install the runscript in /usr/share/runit/sv and maintain a copy of it in /etc/sv/. This is especially useful for packages that provide a large number of runscripts without the corresponding binaries, like runit-services.

COMMANDS¶

a

Copy <service> from CPSV_SOURCE into CPSV_DEST, then create symlinks as when the p command is used; more than one <service> name can be given with this command and each <service> directory must exists in CPSV_SOURCE.
If <service> already exists in CPSV_DEST, cpsv prints a warning, the cp invocation is skipped and the return code is increased by one. The -f option can be used to change this behaviour.

p

Populate the <service> directory with symlinks; a <service> directory in CPSV_DEST must already exist.
If a <service>/supervise symlink or directory is not found, cpsv creates one. If a <service>/.meta/finish file exists, and a <service>/finish file or symlink is not found, cpsv creates a symlink to /lib/runit/finish-exec.
When a <service>/log directory exists: if <service>/log/supervise link or directory is not found, cpsv creates one; if <service>/log/run file or symlink is not found, cpsv creates a symlink to /etc/sv/svlogd/run.

d

Print the diff between the <service> directory that would be created with the a command and the current <service> directory in CPSV_DEST. The exit status of diff is returned; a <service> directory must exists in CPSV_SOURCE. supervise , conf and wtime are excluded from the diff.

s

Sync CPSV_DEST with CPSV_SOURCE; for each <service> directory in CPSV_SOURCE cpsv search the system for a systemd or sysv service file with the same name: if it finds one then it copies the <service> directory as when the a command is given and goes to the next directory; else cpsv looks for the path written in a <service>/.meta/bin file, and if such path exists in the system then it copies the <service> directory as when the a command is given; otherwise it goes to the next directory.

l

List installed services in CPSV_DEST; the name of each <service> that would be copied with the s command is printed, preceded with character surronded by square brakets;
[a]: <service>;
exists in CPSV_SOURCE but not in CPSV_DEST
[i]: <service>;
exists both in CPSV_SOURCE and CPSV_DEST, the copy in CPSV_DEST is identical
to the one created with the a command
[l]: <service>;
exists both in CPSV_SOURCE and CPSV_DEST, the copy in CPSV_DEST is different
from the one created with the a command

OPTIONS¶

-f

Overwrite <service> files in CPSV_DEST with <service> files in CPSV_SOURCE, no backup is provided. When a <service>/log directory exists, the <service>/log/run file or symlink is replaced with the default one that is created with the p command; supervise directories or symlinks are never overwritten or replaced this way.

ENVIRONMENT¶

CPSV_DEST

The environment variable $CPSV_DEST overrides the default directory where services are copied. If omitted or empty, the default is /etc/sv

CPSV_SOURCE

The environment variable $CPSV_SOURCE overrides the default directory from where services are copied. If omitted or empty, the default is /usr/share/runit/sv.src
