   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

  21 ## Making a bootable USB drive
  22
  23 This should work on an external USB drive, ideally one that is 12 GB or greater
  24 in size. Note that using a loop device will probably not work, partly due to
  25 the way syslinux behaves with loop devices. If you get that working, feel free
  26 to submit a patch to <sysadmin@gnu.org>. : )
  27
  28 You'll need to download and install old versions of syslinux:
  29
  30 * <https://mirror.fsf.org/trisquel/pool/main/s/syslinux/syslinux-common_4.05+dfsg-6+deb8u1_all.deb>
  31 * <https://mirror.fsf.org/trisquel/pool/main/s/syslinux/syslinux_4.05+dfsg-6+deb8u1_amd64.deb>
  32
  33 Check files, install them, and run the script:
  34
  35     sha256sum -c syslinux.deb.sha256
  36
  37     dpkg -i syslinux-common_4.05+dfsg-6+deb8u1_all.deb
  38     dpkg -i syslinux_4.05+dfsg-6+deb8u1_amd64.deb
  39
  40     sudo ./live-usb-loader.sh trisquel_9.0-fsf_i686.iso /dev/sdb
  41
  42 ## Installing extra media, including Trisquel 9 source code
  43
  44     sudo ./install-extras.sh trisquel_9.0fsf_sources.iso /dev/sdb
  45
  46 ## Notes about video files and free space
  47
  48 You may wish to transcode the downloaded videos to save space on the member
  49 card, in particular `lp2020_kahle.webm` and `lp2020_younghackers.webm`.
  50
  51     ffmpeg -i foo.webm -acodec libvorbis -b:a 64k -vcodec libvpx -vf scale=-1:720 -b:v 800k -preset medium foo_smaller.webm
  52
  53     # check to make sure that the video quality is okay
  54     mplayer foo_smaller.webm
  55
  56     mv foo_smaller.webm foo.webm
  57
  58 Then optionally update the checksum file for `/mnt/fsf/GNUAV/`:
  59
  60     cd /mnt/fsf/GNUAV/
  61     sha256sum ./ > ../checksums.sha256
  62     mv ../checksums.sha256 .
