Remastering, revisited...

[Makoto]

I'm about ready to try remastering with my Puppy 4.21 setup, but I thought I should check a few details, first...

I have three .sfs files 'installed' in Boot Manager, with the files located on the primary drive, root directory, alongside my pupsave file. Since they're called in Boot Manager, will they be included in the remaster? The same, for everything I currently have installed (the 'normal' method, from .pets)?
That'll then allow me to free up the space the .sfs and .pet files are presently occupying, right?

If the remastering does indeed include everything I have installed in the pupsave file, can I 'exclude' certain programs? For example, I'd like to exclude Firefox and Thunderbird, so I can still point-update them, if necessary.
