|
||
|
|
.SH NAME
|
||
|
|
newroot \- replace the current root with a new one
|
||
|
|
.SH SYNOPSIS
|
||
|
|
.B newroot
|
||
|
|
.RB [ \-i ]
|
||
|
|
.I block-special
|
||
|
|
.SH OPTIONS
|

|

|
||
|
|
.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.
