comment What is kernel ip forwarding?
Typically NAT will work from the LAN to the WAN, so if NIC 2 has a private IP, and NIC 1 has a public 1, you do need NAT; specifically, the internet-facing interface (NIC 1 per above) needs a MASQUERADE rule in iptables's POSTROUTING on a chain to do that. See revsys.com/writings/quicktips/nat.html and i.stack.imgur.com/rzz83.png.

Right, you'll want to do NAT if NIC 2 is a private IP. Linux can do NAT as well and iptables is the way to set it up.

comment Does Android really use the same kernel as Linux?
I said "the kernel is generally just one component in a stack of software ultimately responsible for a user-facing experience" - means not that the kernel's responsible for it entirely but is just playing a part.

comment What are pid and lock files for?
This is correct, unless the lock file is manually deleted. VMWare Player exhibits this behaivor, for example, if VMWare Player crashes, you have to delete a .lck file in the VM's directory otherwise it will tell you it's in use when you try to start it.

comment How to mount a dd-image which was created via fmem (memory dump tool)
The bit from hexdump really looks like the original BIOS/UEFI IDT vectors (before switch to protected mode, seems to all point to 0x00f0XXXX addresses which would be consistent with real-mode environment) anyway.

comment Why is the unit separator (ASCII 31) invisible in terminal output?
ASCII codes under 31, and 127, are intended to cause a terminal or device to do something (hence why they are called control codes), or stand for something in a protocol (like EOT or SOH), as opposed to displaying something. It hearkens back when terminals were typewriter-like devices and things like telling a teletype to carriage-return were physically needed. Editors may choose to render them using "^" notation since you are editing something and don't want to terminal to actually do what the control codes are asking.

comment Can kexec be built to a standalone binary, to be used where kexec was not built into the kernel?
Just for kicks check if maybe you could modify the mtd partition containing the U-boot env vars, but I'm sure that's read only too, right?

comment How to edit /etc/inittab?
From your question it sounds like you weren't saving before exiting Vi. After you are done editing in vi you need to save changes, typically with an [Esc] then w (to write changes), you can combine with q as follows: wq! (write, quit, and ! means don't confirm).

comment What are the platforms that Linux is being used frequently on besides x86?
I'd say after ARM, probably MIPS is the next most prevalent architecture Linux is installed upon due to DD-WRT.
