Package: installation-reports
Severity: critical
Tags: patch
Justification: breaks the whole system
I attempted to install Debian squeeze on my Buffalo Linkstation Live
(LS-CHLv2), as per guidance at
<http://buffalo.nas-central.org/wiki/Install_Debian_on_the_Linkstation_Pro/Live>.
Ultimately I failed, but this report concerns one serious issue encountered on
the way.
The daily snapshots linked from <http://www.debian.org/devel/debian-installer/>
include this script:
<http://people.debian.org/~joeyh/d-i/armel/images/daily/orion5x/network-console/buffalo/lspro/config-debian>
intended to prepare the system for reboot into the Debian kernel. One of the
ways in which this script can fail is that the buffalo version is not fetched
from the environment. However, in this case the script does not exit and
proceeds to attempt to modify the environment. If the users /etc/fw_env.config
is incorrect (as mine was) then this attempt to fetch the version will fail,
and the subsequent modification of the environment might modify an arbitrary
portion of the system's flash memory, potentially rendering it unbootable.
Luckily I noticed this issue when fw_printenv failed for other reasons, and
fw_setenv failed also.
I propose adding an "exit 1" to the script after the error message related to
this issue. For completeness, I would also recommend exiting from the script
if the attempt to back up the pre-existing environment fails. The attached
patch to config-debian includes both changes.
