I noticed that the znode_phys_t has a real creation time - yeah! Okay so how does one get access to that from user land, obviously the standard stat(2) doesn''t cut it. I assume this is read only, ie no amount of privilege can allow you to change this (modulo hacking on the raw disk and fixing up the checksums with something like zdb). I''d also like to suggest an additional time field if possible, the last archived time. This would be upated by zfs backup or by some other user land backup program. This is distinct from the atime, ctime or mtime. I believe this would be useful for CIFS/SMB. One possible way to get access to this might be having them visible as an extended attribute (yeah I know they aren''t stored there but its just a though on using an existing API rather than a filesystem specific ioctl like interface). -- Darren J Moffat
