enroot list -f does not work properly with NFS

[mattgaston]

enroot list -f output displays when container is located on an NFS volume. i.e. ENROOT_RUNTIME_PATH, ENROOT_CACHE_PATH, and ENROOT_DATA_PATH are set to a location on an NFS volume.

[username@node ~]$ enroot list -f NAME PID COMM STATE STARTED TIME MNTNS USERNS COMMAND ubuntu24 <unknown> 1016787 bash S+ 10:52 00:03 4026533122 4026533121 bash

If the container is located on a local volume, i.e. ENROOT_RUNTIME_PATH, ENROOT_CACHE_PATH, and ENROOT_DATA_PATH are set to a location on a local volume.

[username@node ~]$ enroot list -f NAME PID COMM STATE STARTED TIME MNTNS USERNS COMMAND ubuntu24 1019234 bash S+ 10:55 00:05 4026533122 4026533121 bash

This issue occurs on RHEL 8.
