* When a container root process like YUM attempts to create a file owned by a different UID, NFS Server/GPFS denies the creation.
* Does not work with homedirs mounted with noexec/nodev
* User can setup storage to point to other directories they can write to that are not mounted noexec/nodev
* Can not use overlayfs driver, but does support fuse-overlayfs
* Ubuntu supports non root overlay, but no other Linux distros do.
* Support for using native overlayfs as an unprivileged user is only available for Podman version >= 3.1 on a Linux kernel version >= 5.12, otherwise the slower _fuse-overlayfs_ may be used.
* A few Linux distributions (e.g. Ubuntu) have supported even older Podman and Linux kernel versions by modifying the normal Linux kernel behaviour.
* Only other supported driver is VFS.
* Cannot use ping out of the box.
* [(Can be fixed by setting sysctl on host)](https://github.com/containers/podman/blob/master/troubleshooting.md#5-rootless-containers-cannot-ping-hosts)
