FreeBSD walnut 4.4-RELEASE FreeBSD 4.4-RELEASE #2: Wed Oct 16 12:45:39 PDT 2002 root@hw50.decru.com:/usr/src/sys/compile/DISKLESS  i386
>Description:
    depends on the name of the root device, for instance:
"nfs:phungte2:/local/diskless_root" the kernel can returns 1 from setrootbyname() in vfs_conf.c or can crash.  
>How-To-Repeat:
      
>Fix:
      in setrootbyname(), the line parsing the name is currently like this:
      while (cp != '\0' && (*cp < '0' || *cp > '9'))
              cp++;
