.TH NEWROOT 8 "February 1st, 2010"
.SH NAME
newroot \- replace the current root with a new one
.SH SYNOPSIS
.B newroot
.RB [ \-i ]
.I block-special
.SH OPTIONS
.BR "\-i" " Copy mfs binary from boot image to memory"
.SH DESCRIPTION
.B Newroot
causes the present \fB/\fP file system to be discarded and
replaced by the one stored in the device indicated by
.IR block-special .
.PP
The
.B \-i
option may be used to prevent loading the file system
service for the new file system from disk. This is useful when
for some reason the \fImfs\fP binary on disk malfunctions,
rendering Minix unable to boot.
.PP
This command is normally used to replace the initial ramdisk
loaded as part of the operating system, with the operational
version stored on disk. As such, it should be invoked from the
.B /etc/rc
stored in the initial-ramdisk image.
.SH NOTES
.B Newroot
should be used before any "real" use of the
.IR mount (1)
command.
.SH "SEE ALSO"
.BR init (8),
.BR mount (1),
.BR mount (2).
