Hello. I'm new to this list and I don't know if this is the right forum
for my question, but, I've asked this same question on many forums and
never received an answer -- please don't flame me.
I have a Debian based Linux live system which is running out of RAM and
was booted without the "persistent" boot option, so the capser-rw
filesystem was never created.
I wish to gain access to the "upper" directory of the overlayfs
filesystem in the casper init scripts initramfs "/cow/upper" filesystem
so that I may programatically save the filesystem, hopefully without
having to re-implement cp.
I know how to commit the changes of a Debian based live CD session to a
storage device, but only if the live session in question was booted with
the "persistent" option.
I've looked at the overlayfs source code but I still can't figure out
how to accomplish what I want.
I'm sorry if this is stupid question -- hopefully it's not.
