[Ovlfs-devel] Feature: Overlay

[Marten K. <ma...@mi...>]

Hello,

I am interested especially in the overlay feature. I want to hold old data on 
cheap medias like CD or DVD. But the should appear in the working directory 
for the projekt, which is on more expensive (backup) read-write media.

If I understand your overlay filesystem in the right way, it will copy the 
file from the read-only media to the read-write media, when anybody tries to 
write on the file. Is this feature configurable? Could I define some files 
form which this will succeed, while for other files this will not succeed?

With best regards
Marten Karl
