- fanotify is completely silent regarding moves and deletes - it gives no clue something happened. It doesn't catch any other event related to the directories involved (file unlink, for example). Thus, it would need KDirNotify as a complement, which yes, only reports things done via kio.</div>

<div>- The fanotify_init man page confirms that you need root privileges (specifically, the CAP_SYS_ADMIN capability), and says that this constraint might be relaxed in the future. But, at least currently, yes, we'd need a root daemon even to watch $HOME.</div>
<div>- I couldn't get the "directed" mode to work. This is the mode in which you would presumably only receive events from the directories you mark. It should just be a matter of changing a couple of parameters in fanotify_mark, but I didn't get it to work. If it really doesn't work, we'll need to manually filter global events (as I get here about 30 "open" events for /etc/passwd per second, for example).</div>
</div></blockquote><div><br></div></div><div>Ouch. Does filtering on event type work? ie, can you listen to just CLOSE_WRITE events? Also, is it not working, or is it just not working recursively?<br></div></div></div></div>
</blockquote></div></div></div></blockquote><div style><br></div><div style>Yes, filtering on even type works. And listening only to CLOSE_WRITE events filtered a large portion of the non-interesting accesses I was getting here. I hadn't tried that before. But the "directed mode" seems to not work at all. If I try to watch only a single directory, no matter if I list it, touch it, delete it or create a file in it, nothing happens. Maybe I'm just misusing it, but it should be so simple...</div>

I can see instances where a kDirWatch backend might work, if it can perform better than 1 million inotify watches - but I can't see it as a default, because a careless mv or rm would cause problems. <br></div></div></div>
</blockquote></div></div><div><br>Lets use the correct terminology - It's KDirNotify. KDirWatch is KDE's abstraction over inotify, dnotify, fam and others. We do not care about it cause it doesn't support move events.<br>
<br>KDirNotify is the dbus notification api which we care about.<br><br>----<br><br>Since fanotify requires root access, it really doesn't seem like a viable option.<br><br>How about we just stick with just inotify or inotify + kdirwatch?
