quay.io/kanboard/kanboard:v1.2.43 entrypoint.sh: line 12: /bin/s6-svscan: No such file or directory

[hungrymonkey]

Summary

Distros have been unifying all utilities under the /usr dir. This change has broke the entrypoint.sh. The file is hard-coded to search for /bin/s6-svscan rather than /usr/bin/s6-svscan

Suggested fixes.

Remove the /bin and let the shell search s6-svscan in the PATH instead.
