restarts, including when upgraded puma, and is compatible with both
clustered mode and application preload.
**Note:** Any wrapper scripts which `exec`, or other indirections in
`ExecStart`, may result in activated socket file descriptors being closed
before they reach the puma master process. For example, if using `bundle exec`,
pass the `--keep-file-descriptors` flag. `bundle exec` can be avoided by using a
`puma` executable generated by `bundle binstubs puma`. This is tracked in
[#1499].
**Note:** Socket activation doesn't currently work on jruby. This is
tracked in [#1367].
