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.

@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.

comment Where and how are custom startup commands configured in Linux?
No, the question doesn't belong on superuser or serverfault; it is a legitimate programming question which people packaging software for Linux need to know the answer to.
