comment Automount not disabling in Ubuntu 12.04 or 13.04
Can this rule above prevent other udev rules to yet again automount the device? More clearly, does the rule prevent that udev carries out any other rules related to usb memory?

comment Is it possible to prevent files created being world-readable?
thank you very much! now I am a little in trouble as I do need different umask settings for different locations (i.e. in /dir1 I would want a different behavior than /dir2 is this also possible? I will of course consult the Arch wiki linked, but I though you might also be able to extend the answer to this aspect, maybe :)

comment What are the platforms that Linux is being used frequently on besides x86?
compared to x86, do you think ARM is more linux-kernel dominated platform?

comment What are the platforms that Linux is being used frequently on besides x86?
What is frequently? relative (as a percentage of the kernels run on that platform) or absolute (also including the abundance/number of those system themselves)? Relatively I would reckon that ARM might be more linux-dominated then x86. Can you specify?

comment How does the system shutdown of a linux kernel work internally?
+1 thanks! @Gilles if you wanted to implement some code that would wipe/sanatize the RAM of the machine as a laststep you would register a syscore operation for the syscore_shutdown (i.e. that would solve my other question unix.stackexchange.com/q/122540/24394). Step (1) and step (7) both allow to register stuff to be executed at shutdown, not shure what is what + I had the impression the execution order of those callbacks in (1) and (7) cannot be influenced! I will the docs you mentioned, but if you know! thanks!

comment How to have Linux wipe/randomize/sanitize RAM at shutdown?
@StephaneChazelas Thank you again! took me some time to comprehend your hint/comment. I was not very familiar with the kexec command. The idea anyways seems smart, the replacement kernel might be very small, as all it needs to do is to wipe the RAM. Being small it blocks/exempts itself much RAM from being wiped. Do you want to expand the comment to an answer I can accept?

@Kiwy thanks for the suggestion. I will accept after some time has passed for potential better answers to come up. But at least some answer is now there.

comment How to have Linux wipe/randomize/sanitize RAM at shutdown?
@StephaneChazelas thanks for the note on tails. I have looked into it. Maybe I do not completetly understand but it seems they mainly used userspace tools to allocate RAM. What about the potentially more risky parts of the RAM the kernel uses? Even more so the part of the Kernel dealing with LUKS/encryption and keys...?
