@krombel did you see, we already have #5557?

[krombel]

Ohh. I somehow missed it. I saw #5550 which is something different and might have confused the PRs then...

How to proceed now? The other PR in the meantime got outdated. What are the reasons for the other PR not to be merged?
For me it would be OK to merge the other PR and update to 0.18.1 based on the other PR if it is preferred...

Me for my side would intentionally not include resticprofile and probably create a dedicated package for that but add restic independently FWIW
