Exp: on attw

[RobinTail]

The weird postbuild command was introduced in #2374 in response attw failure to work together with npm publish -w (within workspace), see 1b55654

[RobinTail]

I believe running npm pack (which is what attw --pack doing) is not possible in the context of running npm publish as prepublishOnly / build / postbuild sequence of hooks

[RobinTail]

Yep. This hook fails for example when running npm publish --dry-run

"prepublishOnly": "npm pack && ls -la *.tgz"

because npm pack does not really produce the packed file

[RobinTail]

so postbuild with attw --pack is ok for build, but the sequence within prepublishOnly should be different

[RobinTail]

publish does not save the tarball locally

I will have to switch either to #2427 or #2428 to use attw --pack in a workspace directly
