Subject: Optional switching off cow in overlayfs
Date: Thu, 18 Jun 2015 15:25:21 +0200	[thread overview]
Message-ID: <5582C6C1.8080602@samsung.com> (raw)

Hi there!
I was wondering about a small improvement to overlayfs - optional, per 
file copy of write.

1. By default overlayfs would work as usual.
2. If a file in 'lower' filesystem has an xattr set (e.g. 
trusted.overlay.cow=n) the file would not be copied.

What do you think?

Cheers,
Jan
