    If you are booting in persistent mode, you can look in the casper-rw file or partition for changes, all changes are saved there. It is easier to look into a casper-rw partition than into a casper-rw file. Mkusb creates a Persistent drive that uses a casper-rw partition. If you have a Full install to USB you can use something like fswatch, Fswatch is a free, open source multi-platform file change monitor utility that notifies us when the contents of the specified files or directories are modified or changed. Not for beginners. https://www.ostechnix.com/monitor-file-changes-using-fswatch-linux// – C.S.Cameron Mar 31 '20 at 11:59
