myDSL Extensions (deprecated) :: Uninstall a dsl extension

I'm wondering if it could be possible, especially for liveCD and frugal, to somehow make a list of files installed when you install a dsl or tar.gz, leaving them off the list if they over-write an existing file, and then an uninstall option that rm's the files in that list?
This way no core files will be removed, as they could be if you simply made a list of the extension contents and then rm'd those files.  A simple(?) check of file over-write would also mean that if you install multiple extensions, and some of their files are shared, removing one wouldn't effect the other, as the over-written files wouldn't be on the list, as long as you remove them in the reverse order of installation?

So if you load an extension and then, after doing whatever you wanted to do with it, decide you want to free up ram space, you could remove it from the ram drive.

Of course, if an extension hoses the system, rm'ing the extension wouldn't repair the hosed core files, but it's better than nothing?

Recapping in a nutshell:  On install of extension, check if the extracted file overwrites an existing file, if so, fine, if not, add it to an uninstall list for that extension.  To uninstall, select the original extension in emelfm, click a "unload mydsl" button, which will check the corresponding filelist, and rm said files.

But I don't know what happens on file-overwrite, whether you could write a sript depending on it, so...
