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
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. ;-)
