From add39bdb96e82687b0d4c0a7a7cfc0423a2b046a Mon Sep 17 00:00:00 2001 From: Tails developers Date: Thu, 8 Sep 2011 15:48:16 +0200 Subject: [PATCH] Erroring out in case a "wrong" filesystem was chosen. If live-boot finds a "wrong" filesystem that looks OK, then the error message can be pretty confusing. Panic with an explicit message in this case. The "is this rootfs valid" test is implemented by checking if the /usr/share/doc/live-boot/ directory exists: as per Debian Policy 2.3 (Copyright considerations), this directory must exist on any system where the live-boot binary package is installed.
