Change block size on tmpfs

[Sheri255]

I'm using sessions on a tmpfs drive, and I see that my files are 4 KiB in size, although none of them are bigger then 100 bytes, so my question is, is it possible to change the block size of the tmpfs mountpoint to about 128-256 bytes instead, so that i can save (lots of) space there?

edit: Problem (kind of) solved. I had a security script that saved everybodies IP in sessions, to make sure they weren't hijacked. I changed the scripts so that the IP was only to be saved if there were other data in the session. Empty files doesn't fill a block, still, i loose 3.9 KiB on every logged in person, so I'd be happy for a better solution. (changing block size)

This may be way too much work to accomplish what you wish, but would this work for you?

Make a directory for your tmpfs
