like an user of union filesystem modules I completely agree with Erez opinions.

I will say that Overlayfs responds to the needs of a Live system, both for 
daily operations and for making a new remaster also.

It is true that Overlayfs is a young program, and these last few days have 
been found some small problems that Miklos has solved promptly.

According to developers, it is assumed that there are other issues, such as  
links, or the modification of the lower branches of filesystems, etc; but they 
do not appear in a Live system that has been properly prepared taking into 
account those limitations, already documented.

Overlayfs now works correctly, I use it on some computers on a daily basis and 
have not found any problems.

Currently I install all my Linux computers in hard drive copying a file that 
contains the compressed operating system, then the computer uses an union file 
system to boot; that has many advantages and some drawbacks, one of these is 
that the programmer must wait for the corresponding version of the union 
module while a new version of the kernel has been already released; Overlayfs 
has greatly simplified source code and an average user can adapt it to a new 
version making small changes.

For this type of installation no more characteristics are needed in Overlayfs, 
the next step would be to include it in kernel as a staging module. This way 
people will refine some details of its operation and later maybe could add some 
other functionality.

Thanks,
