I'm currently running a swapless debian squeeze install, but i'm going to add swap later (on my SDHC card). I have no need for storage on the SDHC card, as I'm using a USB disk for content / storage. It's an 8GB SDHC card. Any harm in setting the whole thing up as swap? If no, any advantages to NOT setting the whole thing up as swap? Thanks! Loving my sheevaplug
There is no harm will come from have a very large swap. Linux will not use it unless there is need. having this large swap you can create a large tmpfs for compilation of large package. you should set your swappiness
to 10 to reduce OS urge to swap.
and perhaps in /etc/sysctl.conf
vm.swappiness = 10
for long term effect.
If you have lvm then partition your SDHC so you can expand your total storage is good too.
