overlayfs -- the kernel's version, not fuse-overlayfs -- recently learned
(as of linux 5.16.0, I believe) how to support rootless users. Previously,
rootless users had to use these storage.conf(5) settings:
* storage.driver=vfs (aka STORAGE_DRIVER=vfs), or
* storage.driver=overlay (aka STORAGE_DRIVER=overlay),
storage.options.overlay.mount_program=/usr/bin/fuse-overlayfs
(aka STORAGE_OPTS=/usr/bin/fuse-overlayfs)
Now that a third backend is available, setting only:
* storage.driver=overlay (aka STORAGE_DRIVER=overlay)
https://github.com/containers/podman/issues/13123 reported EXDEV errors
during the normal operation of their container. Tracing it out, the
problem turned out to be that their container was being mounted without
'userxattr'; I don't fully understand why, but mount(8) mentions this is
needed for rootless users:
> userxattr
>
> Use the "user.overlay." xattr namespace instead of "trusted.overlay.".
> This is useful for unprivileged mounting of overlayfs.
https://github.com/containers/storage/pull/1156 found and fixed the issue
in podman, and this just pulls in that via
go get github.com/containers/storage@ebc90ab
go mod vendor
make vendor
