Re: [Tracker] About "Linux Kernel file notification" support

[Filippo Pappalardo <filippo email it>]

Jamie, in the past you suggested the possibility to just avoid to do the
scanning of dirs at start up, and I thought it was a good enough idea.

This just because one can assume that it's simply unnecessary to re-scan
everything each time, especially in a system where Tracker is
automatically launched at each login or otherwise consistently used.

You proposed to completely avoid the scan, like Spotlight does in OSX
(please correct me if I'm wrong). Another possible solution could be to
just delay it and make it more "gentle" on the resources (CPU/HD/RAM).
I'd like to know your thoughts and/or plans on this.

Regards
