Subject: [PATCH] app-emulation/containers-storage: add btrfs dep (bug 664574)
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Add btrfs USE flag, and also a device-mapper USE flag.
Use GOCACHE=off to hopefully avoid the reported /root/cache
sandbox violation.

Reported-by: Toralf Förster <toralf@gentoo.org>
Closes: https://bugs.gentoo.org/664574
Package-Manager: Portage-2.3.48, Repoman-2.3.10
