   3 ## Getting the base ISO
   4
   5 This script assumes that you are starting with the special ISO from the
   6 following URL. It already contains video files that the script in this repo
   7 will not try to download.
   8
   9 <http://jenkins.trisquel.info/makeiso-etiona/iso/trisquel_9.0-fsf_i686.iso>
  10
  11 The corresponding source code ISO can be found here:
  12
  13 <http://jenkins.trisquel.info/makeiso-etiona/iso/trisquel_9.0fsf_sources.iso>
  14
  15 Feel free to test your download with the `trisquel_9.0-fsf_i686.iso.sha256`
  16 file in this repo:
  17
  18     sha2565sum -c trisquel_9.0-fsf_i686.iso.sha256
  19     sha2565sum -c trisquel_9.0fsf_sources.iso.sha256
  20
  21 If you want to use a 64 bit image instead, you can get one below, but you'll
  22 have to copy over the `fsf` directory from the image linked above to your
  23 member card. Otherwise, you'll be missing the video files that are included in
  24 the i686 ISO above. The browser window will also currently not launch after
  25 boot on the alternate 64 bit system.

  29 ## Making a bootable USB drive
  30
  31 This should work on an external USB drive, ideally one that is 12 GB or greater
  32 in size, if you want to intsall all of the media files onto it. Note that using
  33 a loop device will probably not work, partly due to the way syslinux behaves
  34 with loop devices. If you get that working, feel free to submit a patch to
  35 <sysadmin@gnu.org>. : )
  36
  37 You'll need to download and install old versions of syslinux:
  38
  39 * <https://mirror.fsf.org/trisquel/pool/main/s/syslinux/syslinux-common_4.05+dfsg-6+deb8u1_all.deb>
  40 * <https://mirror.fsf.org/trisquel/pool/main/s/syslinux/syslinux_4.05+dfsg-6+deb8u1_amd64.deb>
  41
  42 Check files, install them, and run the script:
  43
  44     sha256sum -c syslinux.deb.sha256
  45
  46     dpkg -i syslinux-common_4.05+dfsg-6+deb8u1_all.deb
  47     dpkg -i syslinux_4.05+dfsg-6+deb8u1_amd64.deb
  48
  49     sudo ./live-usb-loader.sh trisquel_9.0-fsf_i686.iso /dev/sdb
  50
  51 ## Installing extra media, including Trisquel 9 source code
  52
  53 This command also updates the Web page that shows up on boot.
  54
  55     sudo ./install-extras.sh trisquel_9.0fsf_sources.iso /dev/sdb
  56
  57 ## Notes about video files and free space
  58
  59 You may wish to transcode the downloaded videos to save space on the member
  60 card, in particular `lp2020_kahle.webm` and `lp2020_younghackers.webm`.
  61
  62     ffmpeg -i foo.webm -acodec libvorbis -b:a 64k -vcodec libvpx -vf scale=-1:720 -b:v 800k -preset medium foo_smaller.webm
  63
  64     # check to make sure that the video quality is okay
  65     mplayer foo_smaller.webm
  66
  67     mv foo_smaller.webm foo.webm
  68
  69 Then optionally update the checksum file for `/mnt/fsf/GNUAV/`:
  70
  71     cd /mnt/fsf/GNUAV/
  72     sha256sum ./ > ../checksums.sha256
  73     mv ../checksums.sha256 .
