Description of the feature request:

Where a startup option is platform specific, currently there is no way to handle it in a single .bazelrc file that supports both platforms.

This would be desired:

startup:windows --host_jvm_args=-Djavax.net.ssl.trustStoreType=Windows-ROOT
startup:linux --host_jvm_args=-Djavax.net.ssl.trustStore=/etc/pki/java/cacerts

A similar syntax and set of built-in platforms to those supported by --enable_platform_specific_config would seem reasonable. I am not suggesting that we support the --config command line for startup.

Which category does this issue belong to?

Configurability

What underlying problem are you trying to solve with this feature?

A single .bazelrc file that can build multiple platforms without needing to 'configure' the file prior to first build.

Which operating system are you running Bazel on?

windows

What is the output of bazel info release?
