Creating symlinks in sources/ does not trigger rebuild

[mikn]

Maybe this is well-known, but I just hit a snag with adding some new defaults to my variant (similar to how you manage your defaults in the core bottlerocket repository) and symlinked it from the defaults folder to the variant defaults.d folder, this did not get picked up by the build system that thought nothing had changed.

Maybe an easy fix? Maybe incredibly difficult? But now you know. :)

I think this should be an easy fix. The process which walks through defaults.d directories is invoked via a Cargo "build script" and lives here.

Seems like we emit a cargo:rerun-if-changed for each input file, but not the directory itself. Per the cargo docs we could emit the directory name for cargo to check every file underneath that directory.

A new tag bottlerocket-defaults-helper-v0.1.1 has been pushed to the bottlerocket-settings-sdk which should resolve this issue. You'll need to consume that as an update to the defaults-helper in your settings defaults package.

Please let us know if you still have issues!
