Bug#932231: flash-kernel might fail silently

[Uwe Kleine-König <uwe@kleine-koenig.org>]

Package: flash-kernel
Version: 3.37
Severity: normal

Hello,

flash-kernel 3.37 introduced the following in flash-kernel:

+	# installation-report #781742 included:
+	#     Can't find /boot/vmlinuz-[...] or /boot/initrd.img-[...]
+	#
+	# It's unclear how this can have happened or what state the
+	# system was in, so log some additional information in the
+	# hopes of catching it in the act next time.
+	(
+		set -x
+		ls -l $kfile*
+		ls -l $ifile*
+	) >> /tmp/flash-kernel-no-kernel-error.log
+	error "Can't find $kfile or $ifile (see /tmp/flash-kernel-no-kernel-error.log)"

A problem here is that if the last command in the subshell fails this
makes flash-kernel exit (as it uses "set -e") without reaching the error
message.

Best regards
Uwe
