Re: [PLUG] Pros and cons of swap in a partition vs. in a file in the file system

dan brings up an important point. no matter what you use, file or
partition, remember that if someone really wants to crack their way into
it, swap can be (semi-)readable. so permissions should definitely always
be kept in mind if it's a file, and lockdown to mount and other assorted
system utilities should always be an important part of your system if
it's a partition (well, they should be locked down regardless).
as for me personally, if it's on an older box, i use swap as a partition
(and as the first partition on the disk, because that has the fastest
spin-up time), usually twice the size of physical RAM. if it's on a more
recent box that i know has enough physical RAM to play nicely, i'll add
a swap partition ("just in case") about half the size of physical RAM
and i'm not as concerned about placement of the partition on the disk,
since at that point swap is just a contingency.

Bill Gates is to hacking as Sid Vicious was to the Sex Pistols: no talent, everyone hates him, and he's just in it for the fame and money.
