14 Mounts the specified container's root file system in a location which
15 can be accessed from the host, and returns its location.

18 If the mount command is invoked without any arguments, the tool will
19 list all of the currently mounted containers.

22 When running in rootless mode, mount runs in a different namespace so
23 that the mounted volume might not be accessible from the host when
24 using a driver different than vfs. To be able to access the file sys‐
25 tem mounted, you might need to create the mount namespace separately as
26 part of buildah unshare. In the environment created with buildah
27 unshare you can then use buildah mount and have access to the mounted
28 file system.

32 The location of the mounted file system. On error an empty string and
33 errno is returned.
