overlay4u - Tools for dealing with overlayfs in ubuntu (Work in Progress)
Simple way to create an overlayfs in ubuntu within Python.
overlay4u requires root. Be sure you're aware of that. It's still very much a work in progress so please use with caution and hopefully on VM that you do not care about.
overlay4u is not currently being designed for anything but Ubuntu 12.04. At this time that's the first priority.
- Mounting works! (Tested and works)
- Creating a table of mounted filesystems
Create an overlay at dest:
import overlay4u overlay = overlay4u.mount('dest', 'lower', 'upper') overlay.unmount()
If the destination already has something mounted it won't mount again:
import overlay4u overlay1 = overlay4u.mount('dest', 'lower', 'upper') # This will throw an error. overlay2 = overlay4u.mount('dest', 'lower', 'upper')
List all overlays:
import overlay4u overlays = overlay4u.list() # Overlays is now a list of all the currently mounted overlays on your # system
Grab a previously mounted overlayfs:
import overlay4u overlay = overlay4u.get('/some_mount_point')
That's all. It's a relatively simple tool.
