    I have 1 GB RAM on my Linux box, and 2 GB swap (0 of which is used).
    But with 260GB of disk space on the computer, why not? I may want to
    run a program that uses 2 GB sometime.

    Is it still also true, though, that swap should at a minimum = RAM (this

    is knowledge that dates back to early versions of SCO, which was weird
    anyway, I know)? If so, then having more swap than RAM may be worthwhile

    anyway, because you probably have plenty of disk space, and you might
    add RAM later (and you won't have to repartition at that point if you
    have extra swap).

    I realize it's also a lot easier to repartition these days, too. But I
    still like to avoid it.

    Can you have too much swap? (Disk space issues aside). If I have 512 Mb
    of RAM, and set up a 1Gb swap partition, did I make a mistake?
