Yeah, that appears to be their problem.
Any user with more than configuration files as data would choke Pinguy, causing that user to be excluded during whatever it does. Ergo, it wont accept your password cause that user no longer exists!!!
LOL - what a joke!!!
My concept of cloning your own private distro is saving all the APP additions and subtractions that you have made to a distro, without making a request for a password, whatsoever. Even that would be a fantasy. Cause trying to copy whatever you got to a completely different computer probably wont work at all anyhow due to differences in drivers and computer hardware.
Ergo, at best Pinguy could be used to restore a distro to the same computer after a catastrophic failure.
What is interesting is that apparently all those Ubuntu installation program files remain on your computer after installation, taking up space.
ALL of this is totally unnecessary with Mint as their software update APP works flawlessly, even for major version updates.
The situation is totally hopeless. These Linux Developers obviously live on a completely different planet from Moi. What they dream up is ALWAYS totally nuts!!!
What might be of value is completely backing up and being able to restore user configuration files as well all the APPs that have been added or subtracted from the standard install; along with the standard install.
If it turns out that Ubuntu Pack distro is worth fooling with, than I would have to manually exclude all of the major directories from Pinguy. Once I got it down to just the basic configuration files, THEN this Pinguy might work. If so from there you could experiment with how much data volume Pinguy can handle. SORRY, but this is ridiculous. That is the job of the program developer. I bet that this amateur Pinguy Guy is still in junior hight school.
From what I have seen, the approach that Pinguy takes would still require you to be online during an Pinguy install; which from Moi's perspective totally defeats the entire point of Pinguy.
Let us face it, the Linux Developers are totally nuts.
To get things done CORRECTLY in Linux you would have to do major amounts of programming yourself, and there is simply not enough time in the universe to deal with all that.
Moi was not born yesterday. As always, screwing around with Clonezilla is probably the ONLY way to go in Linux, at this point.
