Hi all, I'd like to know how I can know the free memory left to allow a software generate a file at var directory. As far as I tested, free command did not to seem to show the exact number of free memory size even if I created and deleted a file. Although I get enough free once I reboot the livecd, I'd like to turn on the system permanently and the free size seems to fluctuate so I'm not sure how much memory I could use to generate a file.
Thanks and regards, Kenji Izutani

It's not yet easy, for rather esoteric reasons. As part of my persistence work, I intend to have a user management tool that makes it easy. Hopefully within a couple weeks so that it can make it into f8t2 or f8t3.
If you really want to research it, take a look in mayflower of livecd-tools, how the copy on write is implemented with devicemapper and tmpfs.
