+switch_root \- switch to another filesystem as the root of the mount tree

+\fBswitch_root\fP [\fB\-hV\fP]

+\fBswitch_root\fP \fInewroot init\fP [\fIarg\fP...]
+.SH "DESCRIPTION"
+.sp
+\fBswitch_root\fP moves already mounted \fI/proc\fP, \fI/dev\fP, \fI/sys\fP and \fI/run\fP to \fInewroot\fP and makes \fInewroot\fP the new root filesystem and starts \fIinit\fP process.
+.sp
+\fBWARNING: switch_root removes recursively all files and directories on the current root filesystem.\fP
+.SH "OPTIONS"
+.sp
+\fB\-h\fP, \fB\-\-help\fP

+Display help text and exit.

+.sp
+\fBswitch_root\fP returns 1 on failure, it never returns on success.
+.SH "NOTES"
+.sp
+\fBswitch_root\fP will fail to function if \fInewroot\fP is not the root of a mount. If you want to switch root into a directory that does not meet this requirement then you can first use a bind\-mounting trick to turn any directory into a mount point:
