Generally you can do it by # mount -t aufs -o br:/tmp/var:/var none /var > Should I make a separate ram disk (different from /tmp which is tmpfs)? > What the correct syntax for this branch(?). Can I put it to fstab? Should > I built a new initrd? - you can use any dir as an aufs branch (as long as it doesn't make a loop with another branch). So you don't have to make a separate ramdisk. - you can write an aufs entry in your fstab if you want - for initrd, it is totally up to + what your initrd does + what you want to do + when your /var is mounted + etc. but generally, if you want to use aufs for /var only, then the above command should be enough. I'd suggest you to check the aufs version in your debian system, since it is known that aufs in debian is obsolete. Also aufs doesn't support linux-2.6.32 anymore. If you want to use aufs on linux-2.6.32, then I'd suggest you to get the last version of aufs2.1-32. Note again, aufs2.1 is not maintained now. J. R.
