hello supergamer,
all ubuntu based distros have a useful advantage from original debian releases: persistent changes. debian releases also have this feature, but appears to be more complex to configure. i explain you details now ...
booting from ubuntu live-dvd, same as loading ubuntu dvd .iso image from hdd or usb, if you have an ext2/ext4 filesystem partition labeled casper-rw into your hdd/usb, that partition will be mounted automatically into ubuntu dvd filesystem at boot. this mean that you can install new ubuntu packages and these packages are persistent at next reboot. installing packages, creating new folders and files and anything you wants to do, like any linux system installed in your machine. if, in the future, you installs any software that halt your machine at boot, you only need to boot your computer with one linux dvd that are not ubuntu based, go to casper-rw partition, save your desired data, and erase folders or format casper-rw partition to have a clean boot from your ubuntu based dvd.
i also used this feature to get new dvd filesystem to remaster ubuntu based dvd's. i maked remasters of ubuntu-12, mint-17, and lite-3. don't want to update and remaster lite-4 because it, like mint-18, request too much ram memory (1.1gb ram only opening file manager after boot at mint-18). my new remaster of lite-3, will finished in few days, only request 385mb of ram at boot after installed all wanted linux software. dvd casper filesystem is 4gb in size. i'm very happy with lite-3. ;-)
