When running this on nodes that have fusermount processes, I encounter the following message and the script returns no information, due to Linux permission restrictions on introspection into FUSE mounts even by root due to security considerations. Is this designed for other types of FUSE usage? ``` # ./fuse-find-host.sh lsof: WARNING: can't stat() fuse.portal file system /run/user/100925/doc Output information may be incomplete. ``` However just running the lsof command that is the first step within the script does return some information: ``` # lsof -Fpf -f -- /dev/fuse lsof: WARNING: can't stat() fuse.portal file system /run/user/100925/doc Output information may be incomplete. p424187 f7 ``` Iʻm wondering why the script fails to return any info apart from this warning in these conditions.
