Whatever its name is, the metas directory is invisible to readdir. It's gratefully skipped every time. >i'm not clear about how the metadata and plugins work. if you write to >..meta/blah there has to be a plugin registered for that meta filename, mjt@shrike:~/..metas$ touch foo touch: cannot touch `foo': Permission denied mjt@shrike:~/..metas$ cd plugin/ mjt@shrike:~/..metas/plugin$ touch foo touch: cannot touch `foo': Permission denied However, there may be big problems with someone mailing attachments named ..metas/plugin/perm and so forth. Also servers which blindly write data to the disk have to be secured. >oes it keep the data in there ("..meta/blah") in some portian of the >normal, linear file? or is ..meta/ the only way to get at it? ..metas/ is completely virtual. It would be great to have some method of having the kernel, the fs, or SOMETHING remember the changes. Or do these changes to plugin settings still stay between reboots? I'd like to hear Namesys' comment here, because I don't know. -- mjt
