In nfsv4, there's a notion of a pseudo-filesystem whereby there's a pseudo/virtual root filesystem. So if you have nfs_server # cat /etc/exports /the/nfsv4/export/dir *(rw,fsid=0) you have to mount this filesystem with nfs_client # mount [ -o nfsvers=4 ] nfs_server:/ import_dir but if you have nfs_server # cat /etc/exports /the/nfsv4/export/dir *(rw) you have to mount this filesystem with nfs_client # mount [ -o nfsvers=4 ] nfs_server:/the/nfsv4/export/dir import_dir as you would with an nfsv3 server. But because it's nfsv4, nfs_server's "/" has an fsid of 0 and you'll therefore be able mount any of "/" "/the" "/the/nfsv4" "/the/nfsv4/export". They are exported as read-only and, even if you mount "/", you wouldn't be able to access the usual directories under "/", like "/usr". _______________________________________________ users mailing list -- [email protected] To unsubscribe send an email to [email protected] Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/[email protected]/message/KB2QX6GS5IPLUWKM3ZYC36GO5FNVCJXI/
