[gentoo-dev] [RFC] check-reqs.eclass: fail check-reqs_memory() for virtual rather than physical RAM

[Christian Bricart]

Dear devs,

i've just hit the constraint CHECKREQS_MEMORY=3G in
>=www-client/chromium-44.* on a 2 GiB RAM machine.. (having additionally
5G Swap on SSD..)

I personally doubt that check-reqs_memory() in the eclass should only
check for *physical* rather than *virtual* RAM to fulfill this
constraint and fail if unsatisfied.

So my proposal would rather be:

* $CHECKREQS_MEMORY<=pysical RAM -> ok
* $CHECKREQS_MEMORY>pysical RAM && <= virtual RAM -> ewarn
* $CHECKREQS_MEMORY>virtual RAM -> eerror (may still be overridden by
${I_KNOW_WHAT_I_AM_DOING} in check-reqs_output() )

what do you think?

cheers
  Christian
