Basically aufs respects all permissions on branch fs and follows its behaviour. Are you using aufs on NFS client with the writable NFS branch, or export aufs on NFS server? Anyway the behaviour of aufs has nothing special. If you want to gain the root access from NFS client, you need to setup NFS server. I'd suggest you to read aufs manual, especially the section "Exporting Aufs via NFS" if your aufs in on NFS server. And next time when you post, provide these info please. (from aufs README) ---------------------------------------------------------------------- When you have any problems or strange behaviour in aufs, please let me know with: - /proc/mounts (instead of the output of mount(8)) - /sys/module/aufs/* - /sys/fs/aufs/* (if you have them) - /debug/aufs/* (if you have them) - linux kernel version if your kernel is not plain, for example modified by distributor, the url where i can download its source is necessary too. - aufs version which was printed at loading the module or booting the system, instead of the date you downloaded. - configuration (define/undefine CONFIG_AUFS_xxx) - kernel configuration or /proc/config.gz (if you have it) - behaviour which you think to be incorrect - actual operation, reproducible one is better - mailto: aufs-users at lists.sourceforge.net Usually, I don't watch the Public Areas(Bugs, Support Requests, Patches, and Feature Requests) on SourceForge. Please join and write to aufs-users ML. ---------------------------------------------------------------------- J. R.
