Is it possible to insert additional lower layers to an existing overlayfs mount?
The idea is to add new features to a running "chroot" so that they immediately see these changes in their root fs and can use them. These features would interleave throughout the fs, so I don't think mounting within that environment would work. For example, a new overlay might come with executables located in
/bin and shared libraries in
If there's some other way to accomplish that then cool. Like maybe some sort of use of namespaces or whatnot...I don't know.
