termux-widget VS proot

Install Termux, Termux Widget, Termux Tasker on F-droid or on the official Termux Github repository.

I use it termux mainly to ssh to a server but also to ssh from my laptop to the phone by running sshd inside termux. By using scp and with the right ssh host config and authorized_keys I can send and receive files across devices, really useful when devices are on the same VPN but not on the same network.

I also use Termux:Widget [1] to launch scripts. For example, I have added all my contacts to abook [2], and with a bash script that use fzf I can filter my contacts and it automatically get the contact gps field and automatically start the navigation.

Please do some research on your own. Start here

From Github Termux, Github Termux Widget download the APKs and install them.

I suspect some component was upgraded (glib?) and it use some functions that are not handled well by proot. Report issue to https://github.com/termux/proot/issues in order to have chances get it solved for yourself and others with this "black screen" problem.

I needed to look at your comment for 10 minutes before I got what you mean. So you want containers that run on any POSIX operating systems?

You can do this with ptrace() which is in POSIX, but its going to be slow for i/o heavy applications. Unfortunately POSIX doesn't provide anything else (seccomp would already be a step up). See also proot[1], gVisor[2] and User Mode Linux[3] which all use ptrace().

Documentation does not exist. Just like in best traditions of open source software typically maintained by one person. Look the proot source code instead. Here is the link to extension source code: https://github.com/termux/proot/blob/master/src/extension/link2symlink/link2symlink.c

You'll probably want to do that inside of a proot environment.

Now regarding proot: it can't have higher privileges than your Termux shell session, despite the user "root" which may possibly appear. It was told many times here on Reddit, Termux GitHub and even Wiki (https://wiki.termux.com/wiki/PRoot) that PRoot does not give extra privileges and root user is fake.

I understand the sentiment, but I disagree. From the last time I checked, the big compromise with GNU/Linux phones is still the lack of social media and messaging apps and appstore ecosystem. Android, with root, is every bit as much a computer as a Pinephone and Librem 5, but the opposite isn't true. Termux has PRoot, a user-space implementation of chroot allowing a full distro install. I personally don't have any problem depending on Google, I have a problem with things being locked away with no alternative. Given the option, I will happily accept the risks and void my warray to root.
