 Implement expansion of special "magic" strings in symlinks into
 system-specific values.  Submitted by Chris Demetriou in Nov 1995 (!)
 in PR kern/1781, modified only slighly by me.
 This is enabled on a per-mount basis with the MNT_MAGICLINKS mount
 flag.  It can be enabled at mountroot() time by building the kernel
 with the ROOTFS_MAGICLINKS option.
 The following magic strings are supported by the implementation:
 @machine    value of MACHINE for the system
 @machine_arch    value of MACHINE_ARCH for the system
 @hostname    the system host name, as set with sethostname()
 @domainname    the system domain name, as set with setdomainname()
 @kernel_ident    the kernel config file name
 @osrelease    the releaes number of the OS
 @ostype        the name of the OS (always "NetBSD" for NetBSD)
 Example usage:
 mkdir /arch/i386/bin
 mkdir /arch/sparc/bin
 ln -s /arch/@machine_arch/bin /bin
