/*

|
|
Given a ref, read its pkglist, inject it in a new commit that is for our
|
||
|
|
purposes identical to the one the ref is pointing to, then reset the ref to that
|
||
|
|
commit. Essentially, we replace the tip with a copy, except that it has the
|
||
|
|
pkglist metadata.
|
||
|
|
|
||
|
|
This is used by tests that test features that require the new pkglist metadata
|
||
|
|
and is also really useful for debugging.
