My point in this assumption was that it's up to the distribution system to
suitably emulate the originator's filesystem so that the result from the build
is exactly what would have been produced if it had been compiled locally. This
is important, for example, for debug symbols, which *do* encode file paths.
We'd have serious trouble if debugging into a function found the corresponding
source depending on the network congestion at the time that the build
happened.

How that happens is out of scope.

And if this can't be properly and reliably emulated, then either the
distributed buildsystem will stop being used or this feature will face serious
issues.
