plural? I only see one package in that bugreport.

It might, if I were able to reproduce this. But I am unable to. It builds
successfully here with the most recent sbuild and linux 4.6. And I see that
Jeremy Bicha made the same experience.

The only confirmed overlayfs problem I ever recall having run into was:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=836211

Namely, overlayfs does not support renaming directories which live in the
underlying file system. But this is not a problem when building packages
because these unpack in new directories. It is only relevant for package
upgrades during the build and that problem can be fixed by either building with
--no-apt-upgrade or by upgrading the underlying chroot with "sbuild-update
-udcar".

So I would not say that it's not stable enough to be used widely yet. This is
also why overlayfs is the default for new directory-type chroots created by
sbuild-createchroot on systems that support overlayfs.

Thanks!

cheers, josch
