The current interface to reset actime uses an ioctl on the file.
If you do it this way, you need root privs in order not to set ctime
with this operation.
Another (ppossible) way to implement this feature would be a open(2)
flag O_NOATIME. There was already a discussion to implement this on Solaris.
BTW: I just checked the source asnd it turns out that the ioctl _FIOSATIME
is not available in ZFS.
It seems that there is a need to enhance the OpenSolaris kernel ;-)
