パッケージ: libcomposefs1 (1.0.8-3elxr1)

mechanism for stacking read-only filesystems (library)

composefs combines several underlying Linux features to provide a very flexible mechanism to support read-only mountable filesystem trees, stacking on top of an underlying "lower" Linux filesystem. The key targeted use case for composefs is versioned, immutable executable filesystem trees (i.e. container images and bootable host systems), where some of these filesystems may share *parts* of their storage (i.e. some files may be different, but not all).

The key technologies used by composefs are: overlayfs as the kernel interface, EROFS for a mountable metadata tree, and fs-verity (optional) from the lower filesystems.

This package contains the library, libcomposefs.
