comment What is the difference between i686 and x86_64?
@toor Certainly if you want to run a single process with 2-3 Gb of private anonymous pages, it gets difficult on a 32-bit OS. Address-space depletion is seriously a problem on such a system, rather than running out of (virtual) memory. However, switching to a 64-bit kernel and userspace is likely to cause the task to consume a lot more ram, perhaps exceeding your target. Maybe in some situations 64-bit kernel, 32-bit userspace is good.

comment What is the difference between i686 and x86_64?
@toor I disagree, 1) 32-bit OSs are able to use more than 4G of ram with PAE etc, which are now standard and 2) Not all of a process's address space may be mapped to (distinct) physical RAM, so it can be useful to have a 64-bit OS even if you have (slightly) less than 4G of ram.

comment How to keep Linux running after hard drive removal?
How about not having a swap file at all? If you've got enough RAM, you're fine. If you don't, you are screwed anyway.
