FunionFS: An UnionFS over FUSE
Author: Stephane APIOU (stephane dot apiou at free dot fr)
Homepage: http://funionfs.apiou.org
Description:
FunionFS is the aggregation of two filesystems: a read-only and a read-write one. The read-only filesystem could be a CDROM or a flash disk for an embedded system. The read-write filesystem could be a Ramdisk or a partition on an USB key ... All datas are read from the read-only filesystem if they are not present on the read write one. Data are written to the read-write filesystem. it's the same principle as the unionfs driver used in the well known Knoppix CDROM.
