Yes, power on the USB is cut but aufs has no problem with this.jemimah wrote:I think booting from usb and then suspending is going to be a problem depending on whether the BIOS of your machines leave power on to the usb port during suspend or not. I've had machines where the built in usb cardreader works great after suspend, but the usb ports do not.
With unionfs I get I/O errors on wakeup. Looks like the power interruption messes up the layering of unionfs.
So, aufs is a good choice. Only that Barry is using unionfs with its 3.x.x kernels...
