termux-packages VS UserLAnd

usbredirect, USB drives/disks, Termux, termux-usb, QEMU, and Alpine Linux in action in April 2024 on an Android 11 phone that is not rooted --> Update-6, Update-7, Update-8, Update-9, Update-10 at https://github.com/termux/termux-packages/issues/19635

Phone (not rooted) running Android 11 and Termux doing superuser/root operations on a USB flash drive connected to the phone, for example "cryptsetup luksFormat /dev/sda1" and "mkfs.ext4 /dev/mapper/v1" --> Update-6 through Update-8 and "Connecting a USB device to QEMU using termux, termux-usb, usbredirect" at https://github.com/termux/termux-packages/issues/19635 (see also Update-9, Update-10, Update-11).

Done on a phone that is not rooted running Termux, termux-usb, usbredirect, and QEMU --> "cryptsetup luksFormat /dev/sda1" and "cryptsetup luksOpen /dev/sda1 v1" and "mkfs.ext4 /dev/mapper/v1" and "mount /dev/mapper/v1 /root/1" where "/dev/sda1" is a partition on a USB flash drive ("dev/sda") plugged in the phone: https://github.com/termux/termux-packages/issues/19635 (github.com/termux/termux-packages/issues/19635'cryptsetup)

Yes. Even without enabling root, you can install Termux[1] and have a full Linux cli environment with ssh.

I agree. I sync my camera folder with Syncthing[1], so as soon as I take a photo it is available on my laptop.

As usual don't forget that Android/Linux isn't GNU/Linux,

With this, I was able to cross compile lone for x86_64 from within the Termux environment of my aarch64 smartphone. All I had to do was obtain the Linux user space API headers for x86_64.

I made a Termux package request for multiplatform Linux UAPI headers specifically so I could cross compile lone but unfortunately it was rejected.

I wonder how far you could get with the git client in termux. I got vim running at one point.

Crystal can be installed with just pkg install crystal. If you have Docker, you could also clone the build environment and try building Crystal locally with scripts/run-docker.sh scripts/build-package.sh -I -a aarch64 crystal.

UserLAnd

https://github.com/CypherpunkArmory/UserLAnd/issues/591 might help?

Actually, you know what, fuck it you're right that's way too many steps I'm just gonna use UserLAnd.

UserLAnd is like a virtual machine app that can run Linux OSes, but can also run specific single apps. And unlike Termux it's a "real" Linux install, so troubleshooting and code from online usually just work. Uses scoped storage of Android 10 unfortunately, but I could still use rsync from the terminal to edit code outside of the scoped UserLAnd application storage and keep the inside updated (on my current device running Android 10). I think they updated to the new 11+ storage standards internally, but it's likely still screwed up on 10 anyways.
