Ubuntu Customization Kit 2.4.0 – Ubuntu a tu medida

Escrito por Ubuntips • 3 Comentarios

Ha sido liberada una nueva versión de Ubuntu Customization Kit (UCK), una aplicación que partiendo de un CD original, nos permite crear un LiveCD personalizado de Ubuntu o alguno de sus derivados, pudiendo agregar o eliminar paquetes, por ejemplo packs de lenguajes, aplicaciones, etc para crear un LiveCd de acuerdo a nuestras necesidades.

Esta nueva versión nos llega con esta larga lista de cambios:

* GUI:
* GUI now uses kdialog, zenity, dialog or builtin (in that order) if available.
* Updated uck-gui to accept parameters for loopback/unionfs mounting and added the possibility to specify a directory different from ~/tmp for remaster-dir. Change is backward compatible to uck-2.2.0.
* Backend:
* Sequence of actions in uck-remaster changed so that initrd is unpacked/customized/packed after the changes to the root file system and the ISO have been done. This avoids problems when customize_iso installs a new Live-CD kernel and initrd (which would previously be overwritten by the contents of the old initrd, causing a mismatch between the kernel (new) and the initrd (old)).
* Extended remaster-live-cd.sh by two procedures to perform loopback+union mounts.
* Added a -m option to uck-gui, uck-remaster, uck-remaster-unpack-iso and uck-remaster-unpack-rootfs that uses a combination of loopback and unionfs mounts instead of copying. This is an experimental feature as of now and not activated by default. It also depends on the packages fuse-utils and unionfs-fuse or aufs-tools, which are not (yet?) pre-requisites for UCK. Documentation for these commands updated accordingly.
* Added two new commands (uck-remaster-mount and uck-remaster-umount) and documentation. These commands are used to do the loopback/unionfs mounts/umounts required by the -m option described above.
* Added code to library for union_umount to kill processes still using files in the mount. This happens when updates start daemons in the root fs.
* Updated all manual pages to reference the source / bug reporting URLs.
* initctl is disabled (replaced with /bin/true) during chroot sessions. With this change is now possible to install mysql/apache and other services in the guest system.
* update-grub is disabled (replaced with /bin/true) during chroot sessions. With this change is now possible to upgrade kernel in maverick too.
* host’s fstab/mtab are copied to the guest so that chrooted “df” can work.
* Backend now checks for kpackagekit as packaging tool, too. Note: This requires that packagekit ist installed on the hosting system – otherwise the dbus queries to packagekitd will fail.
* Added error checking for arguments to uck-remaster-mount.
* improved error checking and handling for union mounts: either all or nothing now; imply -m if tell-tale directory (-cache) is found; made reentrant for use by uck-flow; pointless check for uck-remaster-mount removed; fallback to copy if union mount not possible; do not remove target when using mounts.
* uck-remaster-remove-win32-files now removes usb-creator.exe which was added in maverick
* Fixed immediate umount in uck-remaster-unpack-{iso,rootfs} by trap EXIT handling when using -m.
* unmount strategy (after chroot) was rewritten to unmount every mountpoint found inside remaster-root.
* Package:
* gfxboot-dev dep added for maverick
* Internal:
* New target updman in Makefile to update manual page version numbers.
* Updated localbuild.sh procedure to patch the debian/changelog file so that a local unsigned test version can be generated correctly.
