# Script to remaster Knoppix 3.6; two scripts:
#     1) startremaster, to initialize the source so that it can be
#        modified
#     2) finishremaster, to make the iso image of the modified source
#
# To use:
#     1) boot to the Knoppix 3.6 CDROM
#     2) boot: knoppix lang=us
#     3) copy the files startremaster and finishremaster to the
#        running Knoppix Live CD
#     4) startremaster, to construct the source directory
#     5) if things go well, modify the sources
#     6) finishremaster, to construct the iso image of the modified
#        sources
#     7) if things go well, burn the CDROM of the iso image of the
#        modified sources:
#            cdrecord -v -dev=0,1,0 -data /dev/sda1/knx/knoppix.iso
#        using whatever device your cd burner is on, (use "cdrecord
#        -scanbus" to find out)
#     8) boot to the remastered Knoppix 3.6 CDROM
#     9) boot: knoppix lang=us testcd
#
# There are two long duration processes:
#     1) cp -Rp /KNOPPIX/* /mnt/sda1/knx/source/KNOPPIX, takes about 15
#        minutes
#     2) mkisofs -R -U -V "KNOPPIX.net filesystem" -publisher \
#        "KNOPPIX www.knoppix.net" -hide-rr-moved -cache-inodes \
#        -no-bak -pad /mnt/sda1/knx/source/KNOPPIX | nice -5 \
#        /usr/bin/create_compressed_fs -b - 65536 > \
#        /mnt/sda1/knx/master/KNOPPIX/KNOPPIX, takes about 9 hours,
#        (about two hours omitting the -b option)
# measured on a 466 Mhz. Pentium class machine.
