Hi,
Thanks for Damn Small linux. I am normally a www.Morphix.org user/developer, but wanted a Small linux to fit in my wallet.
Anyway I looked at the Save configuration tool, <filetool.sh>. I also have developed an application from Morphix, cd-persistent. Which allows you to save everything to a multi-session CD.
Last night I modified/hacked this work with Damn Small. Script is below, also available at
filetool_cdrom.sh
Alas, my dsl line is being fixed at the moment, so full script is below.
As the line is up and down like a yo-yo.
Anyway if you record DSL on to a multisession cd using cdrecord :-
cdrecord -multi -data damsmall.iso
(adding -dev=0,0,0 or whatever your device is )
You can then use filetool_cdrom.sh to restore/backup as per the original filetool, to the mutlisession cd itself. Rather than use a flopy/usb stick / HD.
I had some problems using the restore last night as X had been ran before I restored the setting, as I could not run the restore script at boot time. It really needs a remaster, but it was only a quick hack.
Thanks for Damn Small.
Regards,
Brendan Sleight
