Subject: Bail out if architecture isn't set nor can be identified automatically
X-Git-Tag: v0.97~3
X-Git-Url: https://git.grml.org/?p=grml-debootstrap.git;a=commitdiff_plain;h=360e057dcc7b4275db1f5ad6ce66c4aa02a3d2d4

Bail out if architecture isn't set nor can be identified automatically

If `dpkg --print-architecture` isn't available for detecting the current
architecture (e.g. on non-Debian), and neither $ARCH is set nor `--arch
...` was specified, abort and inform user about it.

Closes: grml/grml-debootstrap#173
