do not use absolute paths when accessing files. Use relative paths to the layers root. As part of the refactoring, also drop any cache of the lower layers, working more similarly as overlay in the kernel. Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>
containerfs
An implementation of overlay+shiftfs in FUSE for rootless containers.
Known issues:
Hard links in some cases show different inode values.
Read-only mode is not supported, so it is always required to specify an upperdir and a workingdir.
Usage:
$ containerfs -o lowerdir=lowerdir/a:lowerdir/b,upperdir=up,workdir=workdir merged
Specify a different UID/GID mapping:
$ containerfs -o uid=0:10:100:100:10000:2000,gid=0:10:100:100:10000:2000,lowerdir=lowerdir/a:lowerdir/b,upperdir=up,workdir=workdir merged
