From 23a22d57a8962479ca630c9542e62d6f86fdf927 Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Mon, 12 Jan 2009 14:24:04 -0800 Subject: bzip2/lzma: comprehensible error messages for missing decompressor Instead of failing to identify a compressed image with a decompressor that we don't have compiled in, identify it and fail with a comprehensible panic message.
