Hi, I've been thinking about how I could add a "virtual" directory entry similar to netapp, namely a .snapshot. Obviously I'd want to do this at runtime, but I'm having trouble attacking this problem. I've been looking at the ufs_lookup routines, seems thats the only place to tackle such a feature? Or possibly inject a .snapshot entry as the last entry read in a call to ufs_readdir ? I believe doing a ls -la on a netapp will not return the .snapshot directory, only explicitly nameing the directory will achieve the effects you want. This would be somewhere beneith namei ultimatly in ufs_lookup? Sorry I'm a bit rambling! Cheers, Shanehelp
