Allow mounting via autofs (native) or systemd

Tell us more about this new feature.

Currently, the latest version still doesn't work well with automatic mounting (autofs or systemd).
It fails with following error

The idea is to achieve seamless automatic mounting of buckets while avoiding resource usage when the bucket contents are not being accessed.

Support for autofs was merged in #1762, and will be in the next minor version.

Indeed it is. I found out that there is a PR that does exactly what I need right after I created this enhancement request. I can confirm that when compiled from the source, integration with autofs works as expected.
