Re: [Fedora-livecd-list] hot to figure out the free memory size?

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.
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.
