I have used mondo in the past. They had some trouble transitioning to 2.6 kernels way back when, and then the originators of the project ran into some copyright/ownership/legal troubles. They somehow got through that though, and so they have been working on this issue for a long time. With mindi, you simply edit a file and tell it exactly what files you want on the ram disk that will be the root directory when the CD is booted, so it is very simple to add files, including executables and libraries. In fact, this is how mindi includes utilities, (mdadm, lvm, grub, etc.), for use during a restore. Busybox is used for most standard commands Mindi always uses loopback devices, so all that is required to run it is sufficient disk space. Mondorescue uses mindi to create a boot CD/DVD using your kernel. It then backs up files to media, which can be CD,/DVD, tape, or NFS share. Regardless of what files/directories are backed up, it maintains enough info to recreate partitions and handles restoration of RAID and LVM. It is even possible, during a restore, to convert a single partition into a RAID array or vice-versa and some other combinations of re-partitioning that could be very useful for restoring a system to non-identical hardware in a pinch. Well worth looking into. Its major drawback is that it is Linux-centric and there may not be any reasonable way to port it to other OSs. >> So I think it is a very good approach to make a package or tar file that >> bacula can provide to include in various types of rescue/live cd's.
