Using aufs as a replacement for overlayfs #44

Closed ThibaultLemaire closed 7 years ago

ThibaultLemaire commented 8 years ago

My kernel doesn't provide overlayfs functionality, so I was digging alternatives when I found this article which suggests "patching" your work with aufs.

Further improvement: Patch anything-sync-daemon or goanysync to use a (copy-on-write) union filesystem mount (e.g. http://aufs.sourceforge.net) to keep changes in RAM and only save to SSD on unmount/shutdown (aubrsync), instead of copying all data to RAM and having to sync it all back.

Which makes me want to ask :

First, what exactly does the author mean by "patching" ?

Second, were you aware of the existence of this article, and the alternative to overlayfs it suggests? If yes, why isn't it implemented in your script?

If your distro doesn't compile in overlayfs, you can compile your own kernel or open a feature request with your distro to have them provide it. I have no experience with aufs.
