There was recently a discussion on planet-debian about making BUILDPLACE a
tmpfs. This increases the speed a lot. But then hard-linking of the cached
Debian packages fails. An alternative might be to use the copy action
(APTCACHEHARDLINK = no). But wouldn't it be sufficient to bind-mount APTCACHE
as /var/cache/apt/archives in the chroot?

Could there be an alternative option to APTCACHEHARDLINK: APTCACHEBINDMOUNT?

IMO this would make it easily possible to use a tmpfs for BUILDPLACE.

Additionally, a document about "perf tuning pbuilder" would be nice,
starting from the usage or hardlink for sharing cache contents, to
/var/cache/pbuilder/build as a tmpfs and the bindmount of apt cache
dir into the chroot.

It probably depends on how much memory you have; 2GB or more of RAM
and you'll probably be able to do that reliably.


On the other hand, I personally use cowbuilder, and that seems to be
working pretty well for my use-case.
