pkg/system historically has been a bit of a kitchen-sink of things that were
somewhat "system" related, but didn't have a good place for. EnsureRemoveAll()
is one of those utilities. EnsureRemoveAll() is used to both unmount and remove
a path, for which it depends on both github.com/moby/sys/mount, which in turn
depends on github.com/moby/sys/mountinfo.
pkg/system is imported in the CLI, but neither EnsureRemoveAll(), nor any of its
moby/sys dependencies are used on the client side, so let's move this function
somewhere else, to remove those dependencies from the CLI.
I looked for plausible locations that were related; it's used in:
- daemon
- daemon/graphdriver/XXX/
- plugin
I considered moving it into a (e.g.) "utils" package within graphdriver (but not
a huge fan of "utils" packages), and given that it felt (mostly) related to
cleaning up container filesystems, I decided to move it there.
Some things to follow-up on after this:
- Verify if this function is still needed (it feels a bit like a big hammer in
a "YOLO, let's try some things just in case it fails")
- Perhaps it should be integrated in `containerfs.Remove()` (so that it's used
automatically)
- Look if there's other implementations (and if they should be consolidated),
although (e.g.) the one in containerd is a copy of ours:
