Thanks! I was wondering (related to #56: update github.com/moby/sys/mountinfo to v0.4.0)

Would it be useful to add a replace rule in the go.mod that uses the local code? Something like;

replace github.com/moby/sys/mountinfo => ../mountinfo

That way CI would always test against "tip" (and catch regressions/breaking changes early).

Alternatively, CI could create a copy and add that rule; I recently spotted that it's possible to use an alternative go.mod (which could be a separate step in CI: "verify mountinfo "tip");

-modfile file
	in module aware mode, read (and possibly write) an alternate go.mod
	file instead of the one in the module root directory. A file named
	"go.mod" must still be present in order to determine the module root
	directory, but it is not accessed. When -modfile is specified, an
	alternate go.sum file is also used: its path is derived from the
	-modfile flag by trimming the ".mod" extension and appending ".sum".
