fuse-overlayfs An implementation of overlay+shiftfs in FUSE for rootless containers. # Limitations: Read-only mode is not supported, so it is always required to specify an upperdir and a workingdir. # Usage: $ fuse-overlayfs -o lowerdir=lowerdir/a:lowerdir/b,upperdir=up,workdir=workdir merged Specify a different UID/GID mapping: $ fuse-overlayfs -o uidmapping=0:10:100:100:10000:2000,gidmapping=0:10:100:100:10000:2000,lowerdir=lowerdir/a:lowerdir/b,upperdir=up,workdir=workdir merged
