RELENG_4 documents a config option: options CD9660_ROOT #ISO 9660 Filesystem usable as root but I am unable to find any other reference to this option. I can confirm that CD9660_ROOT is _not_ necessary for 4.10 (at least) boot off a CD-ROM and use it as root. The last reference I can find is in ARCH/ARCH/autoconf.c from whence it was deleted well before RELENG_4_BP. Have I missed something or is this option a total no-op? -- Peter Jeremy
