What is the current behavior?

yarn install --ignore-scripts ignores lifecycle scripts of dependencies.

What is the expected behavior?

yarn install --ignore-scripts should only ignore lifecycle scripts of package being installed. I am not sure if this is intentional but if it is, having a separate flag for just ignoring the "postinstall" of the local package would be very useful (esp. in Dockerfile).

Please mention your node.js, yarn and operating system version.

node v7 yarn v0.22.0

Research direction
Investigate the current implementation of the ignore scripts flag in the yarn install command. Look for where lifecycle scripts are run and how the flag affects them, likely in the src/install directory. Review the comment thread for additional context on desired behavior. Consider proposing a new flag like ignore local scripts or modifying the existing flag to only skip scripts of the package being installed.
