Caution, Knopix live cd (for example) don't have LVM binary or sfdisk command etc... > So thanks to Eric, I now know how to take just about any existing LiveCD or > Rescue disk, open it up, add some Bacula files and generate a new iso. > This gets me out of the bit pushing business of trying to create boot disks > -- just let the distribution do it, and I can write some easy to use > scripts that will add all the nice stuff they leave out. With a debian system, bootcdwrite, bacula-fd, and a big fat kernel you can make an rescue system more easly than trying to customise a Knopix CD. [EMAIL PROTECTED]:/tmp$ apt-cache search bootcdwrite bootcd - run your system from cd without need for disks So, you have to collect system information (partition, lvm description fs type, elabels, etc...) and backup / To restore, you have to : - boot - setup network - get system information - setup disk lvm etc... - restore data (with redirection to /mnt/ for example) - setup grub or lilo and reboot ! After that, you can restore what you want. > Of course, each distribution's CDROM layout is a bit different (Mandrake is > essentially a RedHat ...) so a small amount of knowledge is needed about > each iso, which I can obtain by just looking "inside" the iso. > > What is even better is that this new technique can equally well be applied > to Mac OS X, Solaris, or FreeBSD rescue disks.
