I agree, yet I've become less reliant on the backup file since it hasn't been as reliable as i'd like it to be. I've lost the contents of the backup file on numerous occasions, including the loss of the filetool.lst contents, heck I keep backups of the filetool.lst for such an event, like when updating tinycore versions, then after rebooting finding my perfectly setup filetool.lst replaced with default setup, etc.
Many ways around the dilemma however.. for example one can make the filetool.lst immutable once you have it set up the way you like it. Or make a remastered image with the backup injected., or as the wiki suggests make an extension with one's important configuration files. I use all of the above depending on the type of tc install..
I believe Rich is referring to this command (below), to be used before sudo poweroff / reboot, like I said the above commands are my favorites and iirc were all I needed to install core, configure it, write scripts, test and install them. download, install and update apps/extensions. never needed the filetool backup script in this cli install of core.
