SlothFS is a FUSE filesystem that provides light-weight, lazily downloaded, read-only checkouts of manifest-based Git projects. It is intended for use with Android.
To start the file system:
go install github.com/google/slothfs/cmd/slothfs-repofs
mkdir /tmp/mnt
slothfs-repofs /tmp/mnt &
To create a workspace "ws" corresponding to the latest manifest version
go install github.com/google/slothfs/cmd/slothfs-deref-manifest
slothfs-deref-manifest > /tmp/m.xml
ln -s /tmp/m.xml /tmp/mnt/config/ws
More details can be found in the manual.
