149 The sysfs filesystem is a virtual filesystem that the kernel uses to
150 export internal kernel objects, their attributes, and their
151 relationships to one another.
152
153 Users can use sysfs to ascertain useful information about the running
154 kernel, such as the devices the kernel has discovered on each bus and
155 which driver each is bound to. sysfs can also be used to tune devices
156 and other kernel subsystems.
157
158 Some system agents rely on the information in sysfs to operate.
159 /sbin/hotplug uses device and object attributes in sysfs to assist in
160 delegating policy decisions, like persistently naming devices.
161
162 sysfs is currently used by the block subsystem to mount the root
163 partition. If sysfs is disabled you must specify the boot device on
164 the kernel boot command line via its major and minor numbers. For
165 example, "root=03:01" for /dev/hda1.

584 If you have floppies or hard disk partitions like that, it is likely
585 that they contain binaries from those other Unix systems; in order
586 to run these binaries, you will want to install linux-abi which is
587 a set of kernel modules that lets you run SCO, Xenix, Wyse,
588 UnixWare, Dell Unix and System V programs under Linux. It is
589 available via FTP (user: ftp) from
590 <ftp://ftp.openlinux.org/pub/people/hch/linux-abi/>).
591 NOTE: that will work only for binaries from Intel-based systems;
592 PDP ones will have to wait until somebody ports Linux to -11 ;-)
593
594 If you only intend to mount files from some other Unix over the
595 network using NFS, you don't need the System V file system support
596 (but you need NFS file system support obviously).
597
598 Note that this option is generally not needed for floppies, since a
599 good portable way to transport files and directories between unixes
600 (and even other operating systems) is given by the tar program ("man
601 tar" or preferably "info tar"). Note also that this option has
602 nothing whatsoever to do with the option "System V IPC". Read about
