posixovl: posixovl (POSIX Overlay Filesystem)
posixovl:
posixovl: posixovl provides a filesystem view that supports various POSIX
posixovl: operations while using an otherwise incapable lower filesystem.
posixovl: Filesystems of various degrees of POSIXness can be utilitzed. VFAT
posixovl: is a common  denominator  when it comes to cross-compatibility,
posixovl: though NTFS — its features are unused in Linux — would be another
posixovl: possibility. Secondly, potent native POSIX-style filesystems can
posixovl: also  be used, though the actual use of doing that remains to be
posixovl: discovered.
