lo unico si vas a instalar muchos equipos iguales, y aun asi, seguro que es mas practico algo tipo autoyast.
El autoyast tiene el problema que hay que aprender a usarlo :-p pero la ventaja obvia es que va a funcionar aún habiendo diferencias. Si son iguales, me comentan que los parches que hay que instalar ahora para la 10.2 son tantos que tardas horas en bajarlos e instalarlos, por lo que tirar de una copia de instalación debe ser más rápido. Yo creo que es mejor una copia de seguridad tradicional que una imagen: es más versatil. Y ojo: el G4L, cuando son sistemas de ficheros linux, no usa dd. Mira, del fichero help del G4L de enero pasado (aunque diga 2004 no han cambiado el help): g4l - Gh*st for Linux, Frank Stephen 2004 Version 0.14 - - CHANGES SINCE LAST VERSION - added new menu: - select between RAW mode and file mode ! RAW Node: common g4l mode, copies every single bit of the drive, including empty sectors, deleted files...everything! File Mode: for those people who do not have the time (or space!) to execute RAW mode. This mode accesses the filesystem of the drive and writes only the sectors, which are occupied by files. This is what the commercial products do. As it is senseless to invent the wheel twice, g4l launches the very cool 'partimage' to do this. Be careful: If you need also deleted files and hidden stuff for data recovery or sth like that, use RAW mode ! Check www.partimage.org for info on how to use partimage in detail or from the command line. O sea, que habría que mirar en www.partimage.org para ver realmente cómo lo hacen, g4l es una iso autobotable que lo aplica. Veamos (www.partimage.org): Partition Image will only copy data from the used portions of the partition. For speed and efficiency, free blocks are not written to the image file. This is unlike the 'dd' command, which also copies empty blocks. Partition Image also works for large, very full partitions. For example, a full 1 GB partition can be compressed with gzip down to 400MB. O sea, que no usan dd tal cual. Es una imagen no idéntica bit a bit. Ah! Esto es importante: The partition to restore must have the same size as the saved partition. If the partition is smaller than the original one, the operation will fail. If it is bigger, space can be lost. You can read the FAQ of this handbook, for more details about this. Es importante porque si lo haceis por tener una copia de seguridad, y el disco duro peta, y comprais otro, el nuevo disco no será exactamente igual: seguro que lo comprais mayor, porque por el mismo precio ha pasado tiempo y son más grandes ahora. Y hay que hacer las mismas particiones, e iguales, no da opción a cambiar de idea... yo veo más flexible una copia de seguridad, francamente. Del FAQ: Can I restore it to a smaller or bigger partition ? You can't restore to a smaller partition (you will have an error), but it's possible to restore to a lager one. In this case, some space will be lost (I suppose the OS cannot use all the size). Partimage don't have a resize feature, but you can use other tools. I'd like to add this in the future too. It will allow to restore into a smaller or larger partition. Indeed, as Partimage is low level it uses data blocks. So resizing is possible, but that's a complex feature to implement. With some File Systems made to be easily resizable (as NTFS, ext2, ReiserFS), it may be easy, but with FAT, it's hard to do. For example, when resizing from 1,5 GB to 3 GB, you must change FAT16 into FAT32... You can use GNU Parted to do it. - -- Saludos Carlos E.R. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (GNU/Linux) Comment: Made with pgp4pine 1.76 iD8DBQFGPv0ltTMYHG2NR9URAu8yAJ4l3FtoQuWnWv42ndKUG5IoOEy6gACaA4MQ ZMY61pAO7W9wZGpOmq13GLU= =kVk4 -----END PGP SIGNATURE-----
