Boy am I having fun with DSL so far! Woohoo!

I've got an old laptop that'll only do 800x600, so I managed to remaster using 800x600 values for vga=XXX that'd allow me to boot in 800x600 mode (e.g. *not* vga=791). That worked great!

I also use boot.msg like an /etc/motd to display short messages during boot. (e.g. Hello World). Its easier than fussing with linuxrc. That also worked great!

I included a backup.tar.gz file in the root directory of my remaster containing a custom home/dsl/.xserverrc with 800x600 settings. This worked great, too!

So I boot well and X comes up how I like. Terrific!

But on shutdown, filetool.sh complains with the tar Broken Pipe message I've seen in prior posts.

I only want to run off CD using toram. I'm not interested in saving the filetool.lst info, and since I don't have a writeable restore point, I get the error on shutdown.

How can I customize DSL so I don't go down that codepath? Is it being executed simply because a backup.tar.gz file existed on startup?

I'd also like to learn more about the boot process...
-the kernel loads
-the initrd loads
-linuxrc is processed
-init starts

How can I get into init to see (and maybe modify) what's going on?

Thanks for a great, fun product!

I think that's correct. This should fix your trouble...
Edit /opt/powerdown.sh
There is probably a line that looks like this:
if [ -s /opt/.backup_device ]; then filetool.sh backup noprompt; fi
Remove or comment out that line.
Add /opt/powerdown.sh to your backup archive

The init process is something i haven't studied much yet, but most related files are in /etc/init.d.

You can disable the backup but I think a more appropriate solution and I one I often promote is to call your particular settings something like myconf.tar.gz or mysetup.tar.gz. Then it will restore at boot up and you have the backup system still in place should you later decide to use it. So in your case just rename the backup.tar.gz and your good to go. The existing system design accomodates both methods and I use both a myconf.tar.gz and the backup.tar.gz

Yes,

The ideal solution is to save your custom files that don't change to a myconf.tar.gz file and then save your often changed files (web bookmarks, buddy lists, music files, etc) to your backup.tar.gz via filetool.lst

I found that with older versions of DSL I really needed to keep a spare backup tarball somewhere, in case the real one got overwritten with one using a different filetool.lst. In those days, we had to add Firefox, and so the tarball had a valuable download in it. Keeping a spare may not be necessary anymore, as the filetool.lst one makes in the running DSL system is the one that gets used, and backed up in the tarball itself. Used to be we had to copy the filetool.lst over to the backup partition or device, or you did not have the backup arrangement set up right.
Big improvement with DSL 1.1, especially with the easy to use button in Emelfm to add an item or directory to the filetool.lst.
Knoppix has nothing like this, really, and it is still a manual process in the
Knoppix 3.4 that I remaster. If one does not save your config, nothing happens!
