Exactly. > I can't think of a reason why they would be necessary. Consider for example a single volume nfs server exporting /home. So you want to have updatedb create a subdirectory-local db in /home, so it can be used on remote clients. E.g. you can't assume that every exported volume will be identical to a mounted volume on the server. Every exported dir is subject to create an .mlocate/mlocate.db which for the server itself looks like an ordinary subdirectory. And instead of having to configure it in /etc/sysconfig it is easier to keep the metainformation of about where such .mlocate/mlocate.db should be maintained in the fs itself simply by creating the folder .mlocate. > > Perhaps that way you can even save the explicit mentioning of > > --single-fs paths in /etc/sysconfig/mlocate.

You mean an archive that contains .mlocate? That would be an unfortunate archiving and given that only root can do that it means the admin did it. Same would apply to quota or backup metainformation which also doesn't make sense to archive away. -- Axel.Thimm at ATrpms.net
