This is a one-off with tooling to manage it: from my perspective, I just
kick off the autobuilders etc and they'll automatically use transient
space for objdirs. (And obviously this is all scripted so it is no
harder than making or removing directories would be: typing 'mktransient
foo' to automatically create a dir in transient space and set up a bind
mount to it -- persisted across boots -- in the directory' foo' is
literally a few letters more than typing 'mkdir foo'.)

This sounds like me with tmpfs. Okay, mine don't persist across reboots,
but if it's in your build scripts, can't they create a tmpfs and do the
builds in that?

My system maxes out at 16GB ram, so twice ram per disk as swap gives me
32GB swap/disk by 2 disks gives me 64GB of swap for all my transient
stuff. Running gentoo, I need that space to build gcc, LO etc :-)
