Subject: MAX_ARG_STRLEN too small?

Hello,

I wanted to pass edos-debcheck a big list of packages (10000), but exec
returns E2BIG, because that reaches MAX_ARG_STRLEN which is (PAGE_SIZE
* 32). Comment says “MAX_ARG_STRLEN is essentially random but serves
to prevent the kernel from being unduly impacted by misaddressed
pointers.”

Aren't there other ways to avoid the issue and permit not-so-bounded
args?

Samuel
