         -nfs   [-rootfs]                 LTSP like (28 - 64 Mb)
         -nbi   [-nbi-output=linux.nbi]   Floppy
         -cdrom [-type=grub] [-force]     CDROM

     [-h] or [-help] gentcos extended help
     [-vmlinux=vmlinuz-x.x.x|/boot/vmlinuz-x.x.x] kernel version
     [-suffix=foo] ( suffix for filenames )
     [-size]       ( print ramdisk size )
     [-allmodules] ( generate allmodules-2.6.17-2-486.squashfs to
                             know what kernel modules need )
     [-extramodules=foo,bar] ( add coma separated list of modules )

Or extended help:

# gentcos -help

This is gentcos help info about generating net init images.

 TFTP PXE images:
    -tftp  or [-t] make initramfs-2.6.17-2-486 and copy to /tftpboot/tcos
   [-o=initramfs-tcos1] output file
            ( default /tftpboot/tcos/initramfs )

 NFS (like LTSP) images:
    -nfs  or [-n] make initramfs-2.6.17-2-486-nfs and copy to /tftpboot/tcos
   [-rootfs] Make a complete initramfs and uncompress in /opt/tcos/fs-2.6.17-2-486
            ( default /tftpboot/tcos/initramfs-nfs )

 NBI IMAGES: ( Etherboot floppy )
    -nbi  or [-b] create NBI (network bootable images) in /tftpboot/tcos
   [-nbi-output=linux-tcos1.nbi] output nbi file
             ( default linux.nbi-2.6.17-2-486 )
   [-extra-append] append more options to cmline of NBI image
     ( Example: -extra-append="splash startx=N volume=80%"

 ISO IMAGES:
    -cdrom  or [-c] create cdrom iso file in /var/lib/tcos/isos
   [-type=grub|isolinux] make cdrom based on isolinux or grub
   [-force] force cdrom build if external SQUASH is enabled
           ( this will put squashfs into initramfs )

  In all build you can add this params:

   -vmlinuz=[ vmlinuz.x.x.x | /boot/vmlinuz.x.x.x ]
       this will build all images with the kernel version of this file

 Examples of use:

    gentcos -tftp -suffix=-pc1
    gentcos -nfs -rootfs
    gentcos -cdrom -type=grub
    gentcos -nbi -extra-append="splash vga=791 uselocal"
