subprocess is called in list form with only literal arguments -- nothing
user-supplied reaches the command line -- and the partial `git` path is moot in a
module that only ever runs as root inside middlewared.
Deliberately NOT tagged: this changes no behaviour, and cutting a release for two
noqa comments would raise an update alert on every user's box. main sits one commit
ahead of v0.5.1 until the next real change -- which is exactly the restraint the
alert's docs-only rule exists to encode.
