Ask a Googler about the size of their environment variables.

Ever wondered absl flags library has a --flagfile special flag?

I wonder if ABSL supports gzipped flags...

Probably not, since --flagfile accepts a list of filenames :-)

Does Linux need explicit support for this? Command line arguments and environment variables are copied to the stack of the new process. I would expect the stack's size to be the limiting factor.

Before they relaxed it 15 years ago, Linux had a hard limit at 128KiB for args + env on x86. After the change it was variable up to 2MiB.
