+.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.

+\fBWARNING: switch_root removes recursively all files and directories on the current root filesystem.\fP

+\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:
