link and unlink , urgently...
Hi all
I did something incorrectly about link command.
I try to make a link from a sub-dir to root dir, but I use the following command:
link / zzz
the result is sub-dir "zzz" was linked to "/"
Then I want to remove the "zzz" by using unlink command:
unlink zzz
It say that "Device busy"
I cannot rm nor rmdir. I can only rename it but cannot move it to any directory.
I try to boot to single user mode and try to unlink it again but it still device busy.
What happen to "zzz"
How can I delete the "zzz" without lost any content in my root dir?

APM(8) BSD System Manager's Manual APM(8)
NAME
apm, zzz -- Advanced Power Management control program
SYNOPSIS
apm [-abdlmsSvz] [-f sockname]
zzz [-Sz] [-f sockname]
DESCRIPTION
The apm program communicates with the Advanced Power Management (APM) daemon, apmd(8), making requests of the current power status or placing
the system either into suspend or stand-by state. The apm tool is only installed on supported platforms.
With no flags, apm displays the current power management state in verbose form.
Available command-line flags are:
-z Put the system into suspend (deep sleep) mode.
-S Put the system into stand-by (light sleep) mode.
-l Display the estimated battery lifetime in percent.
-m Display the estimated battery lifetime in minutes.
-b Display the battery status: 0 means high, 1 means low, 2 means critical, 3 means charging, 4 means absent, and 255 means
unknown.
-a Display the external charger (A/C status): 0 means disconnected, 1 means connected, 2 means backup power source, and 255 means
unknown.
-s Display if power management is enabled.
-v Request more verbose description of the displayed states.
-f sockname Set the name of the socket via which to contact apmd(8) to sockname.
-d Do not communicate with the APM daemon; attempt instead to manipulate the APM control device directly.
The zzz variant of this command is an alternative for suspending the system. With no arguments, zzz places the system into suspend mode.
The command line flags serve the same purpose as for the apm variant of this command.
This command does not wait for positive confirmation that the requested mode has been entered; to do so would mean the command does not
return until the system resumes from its sleep state.
FILES
/var/run/apmdev is the default UNIX-domain socket used for communication with apmd(8). The -f flag may be used to specify an alternate
socket name. The protection modes on this socket govern which users may access the APM functions.
/dev/apmctl is the control device which is used when the -d flag is specified; it must be writable for the -d flag to work successfully.
/dev/apm is the status device used when the socket is not accessible; it must be readable to provide current APM status.

HISTORY
The apm command appeared in NetBSD 1.3.
The APM specification first appeared in 1992. The last update to the standard was made in 1996 - the same year when it was superceded by the
ACPI 1.0 standard. Thereafter power management on IBM-compatible personal computers has relied on ACPI, implemented in NetBSD by the acpi(4)
subsystem. The acpi(4) provides an emulation layer for the legacy apm.
