Instead of ONLY this , the following steps may be performed : If the "user" ( being non-"root" ) attaches a device to the computer , the OS looks at a "user" space directory ( imitation of system-wise directory but in the "user" space ) if there is a driver for the device in that directory , it loads and uses it . If there is not any device driver for the device in "user" directory , it looks into the system directory . If there is one , it loads and uses it , else it gives an error message . To manage such "user" space devices , the OS needs to have the ability to look at the "user" space . This may be complemented by removing device drivers from the base system , and making them , let's say , ports or packages . The root loads the necessary ones from the system directories , but the "user" may have the ability to load them from her or his directories . Another important problem is mounting of hard disks connected through a USB port or a hot-pluggable port . Such connections ( excluding if DOS or NTFS ones are permitted implicitly ) require a "root" mount . There is an idea "Use sudo or other super user programs for "allowance" of "root" user" . In my life , I never could understand "How is it possible to manage to protect the security of a system by using such a facility from the "user" space ? " Is it not possible to allow the user to use a mount command for such non-DOS or non-NTFS devices ? Why is it necessary to have a fear about such mounting ? Please do NOT forget that the computer is available to the user PHYSICALLY . He ( let's assume he may use violence ) can destroy , crash , burn , ... , etc. , the computer PHYSICALLY . Such a possibility is not considered , but an innocent "user" space mount is assumed to be harmful . (2) Device definitions are stored as C program data or constant values . Make these as configuration files with ( names which can be generated from the recognized device parameters ) and loaded in run time when it is needed . In that way it will be possible to introduce new device definitions/descriptions/drivers only by copying its device description into the relevant directory whether it is "root" or "user" directory .
