This schroot tip is precious! I have just reduced the build time (which was mostly spent installing dependencies -- I was already using apt-cacher-ng) of a package from ~4min to ~30s! But instead of symlinking /var/lib/schroot/union/overlay/¹ , I configured my sbuild chroots adding union-overlay-directory=/dev/shm ¹ that would affect all my chroots, not only the ones I use for sbuild. I expected the non-sbuild ones to still be there after a reboot. ;-) -- Antonio Terceiro <terce...@debian.org>
