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 | 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 | |
96af59e8 AE |
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 . | |
