first thing (not a nack, just an observation) are whitespace errors:

My git config will fix the errors, but you might want to fix your editor to not include tabs by default in the first place (set expandtab in vim)

Yeah, I edited the file from VM where I do not have my .vimrc installed. Sorry for that.

[jhrozek]

Looks good and works well. We need a test, but that can come in a separate PR. I'll add the Accepted label when CI finishes.

I fixed the whitespace and pushed the commits to master:
