https://github.com/kakwa/puppet-samba
It seems to be somewhat successful, and other people are using it, so I feel kind of responsible to maintain it.
It's not a huge load of work as itself, but for a purely side project I maintain only on my personal time, it diverts time I would otherwise use on other personal projects I'm more motivated to improve.
Another issue is that I no longer use Puppet or even Samba, so I'm not keeping-up with Puppet DSL changes, or Samba configuration changes very well.
I'm also not very motivated in reworking the code to make it better, more reliable, and more maintainable. I merge PR without looking closely, and the code gets progressively more bloated.
I think it's far from exceptional to have a project in this kind of situation so this question could apply to other people:
How to find people motivated to take ownership of a project as a new maintainer?
What would you do? Add a disclaimer in the README.md?
Do you know some website for these kind of requests?
Any proposition (or a new maintainer!) is welcome to step in ^^
