I'd like to move some folders on my computer to a compressed read/write images, so I could get it to take less disk space on my machine (the folders contain some Mercurial and Git repositories). Because I am not using these repositories daily, I'd prefer to have mounting them manually using FUSE.

So far, I've found how to create an empty btrfs filesystem:

dd if=/dev/zero of=/tmp/empty bs=1 count=0 seek=100M
mkfs.btrfs /tmp/empty

How do I mount this folder? When I type $ fusermount /tmp/empty I get fusermount: old style mounting not supported.

    Hello from the future. Just wanted to point out that git archives are already compressed so you will not have gained much space.

looks like you may need to get another package to do that fusecompress is the command listed here.
