[Qemu-devel] [PATCH v2 3/7] docker: debian-bootstrap.pre: print helpful


From: Sascha Silbe
Subject: [Qemu-devel] [PATCH v2 3/7] docker: debian-bootstrap.pre: print helpful message if DEB_ARCH/DEB_TYPE unset
Date: Wed, 24 Aug 2016 20:30:59 +0200

The debian-bootstrap image doesn't choose a default architecture and
distribution version, instead the user has to set both DEB_ARCH and
DEB_TYPE in the environment. Print a reasonably helpful message if
either of them isn't set instead of complaining about "qemu-" being
missing or erroring out because we cannot cd to the mirror URL.
