Hi maintainer, I've attached a patch to the package that we're using to update to 0.52. It seems to work nicely for us.
I've also put a diff of the unscd package which also adds a systemd unit file (#795621) and adds a manpage (#789871) in addition to adding the unit file here just in case that's helpful: https://gist.github.com/chriskuehl/028df2a1b6ee183d104d Obviously feel free to ignore my patches, just including in case they are helpful. Thanks for your work on Debian!
