Package: initramfs-tools-core
Version: 0.130ubuntu3.9
Severity: normal
Tags: newcomer
Dear Maintainer,
When adding "debug" to the kernel commandline debug output is turned on and is
very useful for debugging.  However, none of the scripts (eg. local-premount/resume)
recognize the debug variable to turn on tracing as in init. I simply added the
line "[ -n "${debug}" ] && set -x" as the first line in local-premount/resume
and now I get debug logging when the debug kernel parameter is added.  This line
should be added to all scripts, or at least the scripts run by "run_parts".

I think this would be a surprising interpretation of the "debug" kernel
parameter, and it could leak sensitive information to the screen.  So I
won't be making this change.
