Greetings -

I am new to DSL and absolutely love it! I also understand the 50Mb limit for the distribution.

I am looking for a definitive answer as to whether it is possible to combine a backup tarball with an iso image of DSL. Obviously this will not fit on 50Mb media - but I do not want to change or re-master the original DSL distribution. I want to keep the distro absolutely clean.

I have used a tool (MagicISO) to open the distro iso image and simply add the backup tarball to the root directory of the cd. Saving the iso and burning it to media results in a working "live" cd of DSL, but the boot option "dsl restore=scd0" or permutations of this command do not work.

The error seems to be that the distro only looks for the backup tarball in the /mnt or /etc/fstab locations. When I inspect the /CDROM mount point, I see the expected contents, but I would like to know how to get the distro to look at this location - or something that chains to the actual boot cdrom media for its restore option. I would much prefer *not* to change the core distro itself.

I hope this explanation is understandable. I want a way to bundle the clean DSL distro and my custom configuration backup file on the same media.

My attempts at re-mastering have been a total failure. I would be happy with just a "/static"/ backup config on the boot CD.

Thanks in advance -

Joel Lieberman

you'll need to unpack the iso with something like Gnomezip or WinRAR. then just drop your backup file in there and repackage the iso.

or you can use the myDSL script, but I'm not sure how that would work.

Thanks for responding. I have already added the backup tarball to the iso image (CD root directory) using WinISO.

The problem is that the DSL will not look for it since it only looks in /mnt for the mount points, and these do not include the CD at boot time. If I could get remastering to work, I would try to set up an additional mount point in /mnt that points to the CD, but I have not been successful with remastering.

If anyone knows how to get the boot process to look for the backup tarball on the CD, I would be grateful for the information.

Thanks again -

Joel

if you have enough ram, you could do this at the boot command line.

Code Sample

dsl toram restore=/cdrom

but once again, i haven't tried this so no guarantees it'll work.

I tried your suggestion but DSL complains that it cannot find /cdrom in the fstab or other default filesystem descriptor files.

I guess what is needed is an additional default (and mounted) entry in fstab and /mnt. Something like /mnt/scd0 or whatever is needed so that the "restore=/mnt/mountpoint" will be recognized as a legitimate backup location (read-only of course).

Thanks -

Joel
