Sigh. You would think there was a tar somewhere. But not as of 2007-06-01. |

Alternatives: |

Approaches: |

*Recursive wget of http://dev.laptop.org/pub/content/library . But because of the way the library is structured, you need to |

and then grovel over dev.laptop.org/pub/content/library/sidebar.html |

to obtain the sections. |

perl -ne 'next if !m#(\w+)/index.html#;print "http://dev.laptop.org/pub/content/library/$1/\n";' < dev.laptop.org/pub/content/library/sidebar.html|sort -u > deleteme |

cat deleteme | xargs -n 1 wget -r |

But, then you would need to chase after more directories. Punt. |

Xen Player
Is anybody doing such an emulation? Nitpicker 21:59, 5 October 2006 (EDT)

Temporary summary of current state
currently: quickstart is a "choice of livecd/sound/no-library/read-only or qemu/non-devel.img/no-sound/library/read-write". and devel is "mix of qemu/livecd.iso/sound/ro and qemu/-devel.img/no-sound/rw". MitchellNCharity 13:06, 24 May 2007 (EDT)
Wiki maintenance - how to build needed images
The two flavors of iso/img's we really want to give visitors are not regrettably generated automatically. This section describes the attempt to create them. MitchellNCharity 22:47, 1 June 2007 (EDT)
Modified .iso LiveCD - adding the olpc Library
The LiveCd is intended for development, and thus doesn't include the Library sample content. One wants the library when demo'ing sugar. Here is how to add it.
The LiveCD is currently created manually every month or two.
Getting /home/olpc/Libary
Alternatives:
- Snarf a copy from an xo disk image (the ext3.img variety).
mkdir tmp_img mount -o loop,offset=33174 olpc-redhat-stream-development-ext3.img tmp_img
The Libary is in tmp_img/home/olpc/Library. The offset=NNNNN may need to be adjusted. See Emulating the XO/Help and tips.
- As of 2006-06-01, there is a snapshot:
wget http://dev.laptop.org/pub/content/lib-4-6.tar.gz
Get squashfs
Get squashfs. On fc6,
yum install squashfs-tools
Add the library
wget http://olpc.download.redhat.com/olpc/streams/sdk/latest/livecd/olpc-redhat-stream-sdk-livecd.iso
As root
mkdir tmp_iso mount -o loop -t iso9660 olpc-redhat-stream-sdk-livecd.iso tmp_iso /usr/sbin/unsquashfs -dest tmp_squashfs tmp_iso/squashfs.img # about 4GB
file tmp_squashfs/os.img ## tmp_squashfs/os.img: x86 boot sector; partition 1: ID=0x83, starthead 1, startsector 62, 8388290 sectors, extended partition table (last)\011 ## 62 * 512 = 31744 mkdir tmp_os mount -o loop,offset=31744 -t ext3 tmp_squashfs/os.img tmp_os
mkdir tmp_os/home/olpc/Library (cd dev.laptop.org/pub/content/library/; tar cf - .)|(cd tmp_os/home/olpc/Library; tar xf -) chown -R 500:500 tmp_os/home/olpc/Library
umount tmp_os /sbin/mksquashfs tmp_squashfs squashfs.img.new
mkdir tmp_iso2 (cd tmp_iso; tar cf - .)|(cd tmp_iso2; tar xpf -) umount tmp_iso mkisofs -v -r -T -J -V 'Modified LiveCd mumble' -l -R -c boot.catalog -b squashfs.img -o new.iso tmp_iso2 ##XXX - wrong - doesn't work
Notes:
- Unfinished.
- Could be cleaned up. And parts copied out into Help_and_tips.
