We won’t apply this patch because in general there’s no reason for build
processes to require /var/tmp (we’ve never encountered that.)

That said, are you sure you want to use
--with-store-dir=/var/tmp/xxxxx/gnu/store?

You probably got a ‘configure’ warning already that certain things may
not work, for instance that the shebang max length may be exceeded.

Also using a store other than /gnu/store means you won’t be able to use
substitutes, nor to compare build results with other machines.

Thanks,
Ludo’.
