multiple sources folder view

[Dj YB]

hello,

is it possible to configure a folder in Dolphin or any other way to show the 
content of multiple sources?

for example the folder ~/Movies will show the content of the folders
/mnt/Disk-500/Movies
/mnt/Disk-250/Movies
~/Downloads/videos

writing to ~/Movies would write to a specified location, possibly one of the 
mentioned above.

I saw it in Win7 and thought it could be very useful.
thanks,
YB.

You just described the UnionFS concept ;-)
  http://www.filesystems.org/project-unionfs.html

While it's actively developed (upto 2.6.34), it's not in (official)
upstream kernel and as a result, not included in fedora.
[it's used by Knoppix for a log time]

Alternatively, there's a fuse (Filesystem-in-USErspace) implementation:
  http://podgorny.cz/moin/UnionFsFuse

It isn't packaged for fedora, but maybe someone (you?) may want to do it.
I found old packages on Dag Wieers and Dries repositories which may
help you as a starting point:
  http://dag.wieers.com/rpm/packages/fuse-unionfs/
  http://dries.studentenweb.org/rpm/packages/fuse-unionfs/info.html

Unionfs-1.x is from 2004-2006. Maybe they borrowed it ;-)

If it's not there and you can't see it, it's GONE!

thanks, that is really what I meant.
this is strange, I can see there lots of distros that are using this like 
OpenSUSE and Ubuntu but not Fedora/CentOS/RedHat... why?
it seems like something very basic.

how do I build this?

YB.
