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...?

comment Guide how to configure D-Bus safely?
not particulariy helpful but yet still a start is this dbus.freedesktop.org/doc/dbus-daemon.1.html A guide as asked for in this question would be essentially the same but (1) with examples and (2) easier understandable

comment Which Desktop Environments do not require D-Bus?
@strugee to quote a comment line in an dbus config file(bluetooth.conf on a Ubuntu 12.04LTS) <!-- ../system.conf have denied everything, so we just punch some holes --> it seems they work quite somewhat distinct. At least permissions do not try to poke whole put to avoid them. also permission are done via chmod mostly. With D-Bus I am XML file editing. A D-Bus less DE hence would reduce the workload. I could only focus on file permissions and restrict processes via LSM.

comment Which Desktop Environments do not require D-Bus?
The portability seems to be at the expence to more effort in configuration. Thanks to stuff exposed via D-Bus there can be plenty of additional attack vectors, or else a heavy configuration effort has to be done to keep up safety. As obvisiouly the D-Bus way is ignorant of the file permissions. Stuff not available via filesystem might be accessible via D-Bus. There must be people who dislike this and hence favour a no D-Bus DE, right?\

comment Which Desktop Environments do not require D-Bus?
Given that there are so many ways for communicating unix-sockets, pipe, shared files etc... I was and am still hopeful somebody can find somehting. Or maybe there is a good reason why D-Bus should always be the best solution?

comment Guide how to configure D-Bus safely?
@Braiam In some sence this question "Dbus: is there such a thing as a “Dbus sniffer”?" gave me reason to think D-Bus = risk? => need to configure safely!

comment Guide how to configure D-Bus safely?
@Braiam indeed I did. I nonetheless wanted to add a refenrence that gives some reason to why I expect a safety configuration to be necessary. I could imagine that some risks (i.e. data sniffing) could happen (i.e. from skype via Dbus). I will try to find or add better examples. By the way thanks for the edit!
