The ncurses interface forgets some of the entered parameters (like username and password) in between runs of g4l (not reboots, I know it's a in-memory Linux system). It should save these in a file somewhere so that when you reenter g4l from the command line it reuses the previous parameters by default.

That would be possible, but would have to look at it. The options are parsed thru files in the /tmp directory, but having it check each one would require some code. Generally, what I have done, is use the front end option, where it downloads a script from the ftp server that has most of the options already set. This includes the fg4l and other versions, that cam encrypt or place the script in a users directory. I also have it make the filename to include the date, so it is simple to make versions of backups. I also generally don't run another version of the script, but use the cancel option to go back and change things if I am backing up partitions.
