I used to run a full Debian chroot on Android. It was very handy except that if you ran it on an unrooted Android device you couldn't be a user with full root capabilities. But gcc, make, tar, gzip, and git worked well enough to compile working stacks for other languages (the first software I built on it was Perl from source) as a regular user. Thousands of packages available and the ability to build from source, right on my phone in my pocket. They had other distros for it, too. Unfortunately that project - GNURoot - seems abandoned. Possibly fortunately a new one is from the same maintainers. I think I never used X on it. https://play.google.com/store/apps/details?id=tech.ula&hl=en_US&gl=US https://play.google.com/store/apps/details?id=tech.ula&hl=en... There's another called Debian noroot (https://play.google.com/store/apps/details?id=com.cuntubuntu&hl=en_US&gl=US https://play.google.com/store/apps/details?id=com.cuntubuntu...) that appears fairly up to date but I haven't tried it. It's well rated but said to be slow. It includes XFCE and apparently starts it by default. It uses PRoot. https://play.google.com/store/apps/details?id=studio.com.techriz.andronix&hl=en_US&gl=US https://play.google.com/store/apps/details?id=studio.com.tec... is yet another, and also uses PRoot. I have concerns about their page saying they have closed-source modded versions of F/OSS operating system distros though, and that they'll only provide source to developers who register with them. That's kind of unneighborly if they're customizing BSD or Apache licensed portions of a distro and illegal if they're doing it with GPL or LGPL portions.
