I find that statement kind of funny. True, swap used to be flaky. But,
luckily, the developers didn't just give up; they actually made it work
(for most people)!.

Another option is to use tmpfs, if you have some RAM to spare.

I do this routinely. I have shared a single swap partition between at
least 2 or 3 of the following on at least 3 of my machines:
* Ubuntu 4/5/6/7
* Xandros 2/3/4
* SuSE 9/10
* Mandriva 9/10/2007
... and more besides. I review and write about software for a living,
amongst other things. Most of my PCs boot into at least 2 different
distros: that way, if one gets screwed up, I can use a different one
to fix it.
However, the caveat you've been given applies: *do not* use
hibernation if several distros share a single swap partition. If you
restart a different distro, Bad Things would be very likely to happen
and might destroy both distros.

You don't even need RAM - tmpfs uses virtual memory, so I make a big swap
file and allocate a GB to /tmp.
But what I meant is that the occasional app actually checks for a file to
have been left in /tmp when it starts up - and if you've rebooted there
shouldn't be one (and certainly won't if /tmp is on a tmpfs).

Bad Things shouldn't happen. You boot, it checks swap for a hibernation
signature, compares it to the running kernel, and aborts the resume if the
kernels differ. I'm not sure what it does you boot the same kernel with
different root partitions (I'm not stupid enough to try...), but one would
hope it does the same.
In any case, even if the resume is aborted, you're then booting into a
situation where it's as if you powered the machine off without going
through a proper shutdown, but all the filesystems were synced before
hibernating so nothing terrible should happen.

Hmm! Cogently argued. I confess I've not tried this; I only have 1 PC
notebook specced well enough to run Linux and it won't due to a broken
ACPI implementation. So, I've reluctantly reverted to Win2K Pro on it.
Never tried Linux suspend & resume; it doesn't work on that hardware.
But you make your point well, so I bow to your superior knowledge!
I am using Fedora 10,1GB ram,80 HD,Intel(R) Pentium(R) D* CPU
2.66GHz..
Thanks.

Use a usb-stick, formatted as swap.
It will be made use of on boot up.
I have four machines using them (up to 4gb sticks)
ymmv

Please do not send html emails
you can either get rid of windows and use that space (I know, cheeky)
or look at adding a swap file.

Hi,
You can try this:
1- Create a swap file (use this if you can't change your partition layout) via the command:
dd if=/dev/zero of=/tmp/swap_file bs=1024M count=1
2- format the swap file with :
mkswap /tmp/swap
3- add the new swap file swap system
/sbin/swapon /tmp/swap_file
4- make the swap load on boot loading
echo /sbin/swapon /tmp/swap_file >> /etc/rc.local
Regards
