By whom/how are permissions handled? Even if it's symlinks, the original files in /devfs have to carry them (you can't follow symplinks to files you can't access directly!). And that means the kernel has to know how to set up permissions for a new device when it appears, and remember the settings from one boot to the next. Gross. And a kludged initscript that sets them up on each boot is even worse. As bad as the much-maligned MAKEDEV, but run _each_ boot, so much more critical. -- Dr. Horst H. von Brand mailto:vonbrand@inf.utfsm.cl Departamento de Informatica Fono: +56 32 654431 Universidad Tecnica Federico Santa Maria +56 32 654239 Casilla 110-V, Valparaiso, Chile Fax: +56 32 797513
