Tracking a problem (Internet oddness)

This looks like a recursive issue and a file is locked, me thinks.

acpi-support (0.109-0hardy2) hardy-proposed; urgency=low

  [ Jakob Unterwurzacher ]
  * Defensive quoting in 90-hdparm.sh, so that the script doesn't throw
    a syntax error when the battery state is undetermined.

  [ Steve Langasek ]
  * lib/power-funcs: refactor getState() to return 'AC' by default,
    since this is implicitly the case if we don't have a battery.

    LP: #59695.

I would blame quantum entanglement for this problem, but it seems that it may be intellectual entanglement and my mind is operating faster than my ability to understand.

# This script adjusts hard drive APM settings using hdparm. The hardware
# defaults (usually hdparm -B 128) cause excessive head load/unload cycles
# on many modern hard drives. We therefore set hdparm -B 254 while on AC
# power. On battery we set hdparm -B 128, because the head parking is
# very useful for shock protection.

I am not exactly sure where the problem arises, however this is the change and as such, I am not liking things that stop the ability to get to console as it requires I fiddle from another partition and that is icky. Below is the defensive quoting.

if [ "$DO_HDPARM" = y ] ; then
if [ $DO_HDPARM = y ] ; then

On top of that there is some weirdness going on with Firefox and it isn't minor. It appears to be a security hole and I don't even want to mess with that until I have resolved this. It results from a game that people play with image files and others may not be aware of it yet. I was trying to get a good example of it to test with. It is possible to make images un-copyable or worse , however the bandwidth is severely affected. I am really getting tired of the internet copyright wars and I may just go text mode and use a tunnel if it gets too bad.

I am reasonably sure there is some odd recursion going on and it is a matter of analytical skills is why I do it. It verifies that my CPU is running fine if I solve and understand problems. :)

I finally gave up and just killed the process as I think it went into an accidental deadly embrace. It works fine and it is just an issue for me as I was using "proposed" updates. I had fun digging in /sys and /proc a little bit.
