I find it annoying that I leave a trail of .DS_Store files whenever I use the Finder with disk volumes over NFS, such as on a Unix server. (This is the file the Finder uses to store display information for each folder.) Luckily, I found an Apple Knowledge Base article that tells how to avoid it. Just type Code: defaults write com.apple.desktopservices DSDontWriteNetworkStores true in Terminal, for each user account. After that, .DS_Store files won't be created for remote file servers under NFS, SMB/CIFS, AFP, or WebDAV. Just thought I'd pass the tip along.
