.TH ROOT 3 .SH NAMEroot \- the root file system.SH SYNOPSIS.nf.B /.B /chan.B /dev.B /env.B /fd.B /net.B /net.alt.B /nvfs.B /prog.B /root.B /srv.B /osinit.dis.fi.SH DESCRIPTIONThis device is set up by the kernel to be the initial root ofthe name space.In the emulation environment,the names in the one-level tree shown above are mostly just place-holders,to allow a place on which to.I bind(see.IR sys-bind (2))..PPIn the native environment, an arbitrary initial directory structure andfile content can be built-inwhen the kernel is configured, but it will typically include at leastthe names above, to act as mount points.(See the discussion of the `root section' in.IR conf (10.6).)The required file.B /osinit.dis(not present in the emulation environment)provides an executable Dis binary when read,and is the first program invoked when initialising the system.Other files needed for bootstrapmight also reside in this device..PPIts local name.B #/can be used by programs outside the kernel, for instance to implement.B newnsin.IR newns (2)..SH SOURCE.B /emu/port/devroot.c.br.B /os/port/devroot.c.SH SEE ALSO.IR init (8)
