Je viens de tomber là dessus :
Description: Unionfs modules for Linux 2.6.17 on PPro/Celeron/PII/PIII/P4
This package provides the Unionfs modules for the Linux kernel version
2.6.17 on Pentium Pro/Celeron/Pentium II/Pentium III/Pentium 4 machines.
.
The unionfs driver provides a unification file system for the Linux
kernel. It allows to virtually merge the contents of several directories
and/or stack them, so that apparent file changes in the unionfs end in
file changes in only one of the source directories.
En clair, ça sert à quoi ? Quel usage pratique ?
