My remastered fd64.sfs is exactly what I want. Its using a directory for saves. As I experiment in the cryptosphere taking on scammers I know that security is paramount. So I made a new root password that was super difficult. Resulted in being forgotten after two weeks of not using the system. I even forgot the previous password. I tried to alter the contents of the savefile but without success. So this is what i did to keep my system and change the password without knowing the old password.
1) Boot the system with a base.sfs with known or no password.
2) Extract the remastered base sfs to a directory.
3) chroot into that directory.
4) type passwd and follow instructions.
5) exit chroot
6) recompress that directory to fd64.sfs
7) copy it to your boot partition, replacing previous base sfs.
8) reboot without savefile
9) change password again using same password as latest.
10) quit system creating new savedirectory on shutdown
11) reboot and copy contents of new savedirectory to old savedirectory
12) reboot system with old savedirectory.
That worked for me!
