[indiana-discuss] Strange behavior when I open a folder in file browser

[Trond Norbye]

Opening a folder located on my Desktop in File Browser is incredible slow, and today I tried to attach truss to nautilus before opening the folder. I was really surprised by what I saw:

[ ... cut ...]

This caused the automounter to mount _ALL_ the users in my auto_home, and all I wanted was to look at the content in /home/trond/Desktop/foo ..

Why does it need to stat all of the directories in /home?
