I have to set up a machine as dual boot 32/64 bit and I would really love to not waste space on swap partitions being duplicated if I don't have to. That said, if I do two installs and use the same swap partition, what evil will come of it?

No problems. I do it all the time when testing/switching between different Fedora releases.

The only obvious issue I see is suspending the non-default kernel and trying to boot the other (found that in FC6) and I can avoid that. Any other know issues I have to avoid?

Yeah, you definately don't want to hibernate to swap on one OS and try to boot the other. You'll just lose your hibernated system and leave the filesystems in inconsistent state. In general it is very bad to boot /anything/ other that the original hibernated kernel when after you have hibernated. That's why grub doesn't show you a menu when you boot up in a hibernated state.

_I_ don't think I'd like that. I _can_ hibernate Windows, run Linux, then resume Windows. I've not hibernated Linux at all except accidentally (FC3 I recalled resumed then shutdown, I lost interest then).


The object is to run one 64 bit program without reinstalling the whole stable 32 bit environment.

Why not go all 64-bit? I've been using it, and have had zero issues with 32/64 bit compatibility.

I've been running pure 64-bit Fedora and SL5 with no problems that concerned me: I don't know what, if any, browser plugins work, and don't really care. I don't like flash!

What has "like" to do with it? Both my professional (meeting replays and training sessions) and personal (news) life requires both flash and realaudio. I can't really see remaining ignorant of what's going on in the world because it's not served on the right format. And I sure can't see having a Windows machine just to keep informed.

I really can't see ignoring things I don't like, ignorance is *not* bliss, old sayings aside.
