I just summed up the 2 example packages here.

I do see your concern about the filesystem/mountpoint layout.

If it's a single /: that needs 850M
If it's split / and /opt: then it's the listed space in each location.

Correctly processing this would require converting each of the listed
check locations to their common mounts, summing the needs, and then
validating.

This should be possible with "stat --printf=%m" to resolve any directory
into it's mountpoint.

I'll see if it can be done trivially enough for the eclass.
