If the child is really young, check out the sugar desktop environment. There is an official distro from sugarlabs and there is also a fedora spin (fedora soas)
If the computer should be a little more functional, the GNOME desktop or the Deepin desktop are good options imo

As far as I know, no. But you can from mastodon, pleroma, or other similar microblogging oriented software

Although the most active instance by far is pixelfed.social, that shouldn’t be relevant as you can interact with any pixelfed or mastodon account/posts no matter the server you join. So, you could join any pixelfed instance and follow the mastodon.art (most active multimedia instance) users, for example

@elscallr I agree about the instance configuration, fixing that is the real solution
My question was not about running something as another user, but about hiding the superadmin privileges from a single command I’d execute without switching users. However it is clear that something like that doesn’t exist so I’ll do the right thing and set everything to work with a new user

@ursakhiin honestly, I didn’t even know an aws instance could be a docker image. Everything I did was creating the instance normally so I assumed it was just a regular vm. But already double checked and it is not a docker image, so no problem there 🙂

@ursakhiin honestly, didn’t consider it. Just checked and the “docker” command doesn’t even exist so I assume that is not the case. Do you know if the is any other way I can be certain?

@Oisteink yep, that seems the right thing to do. Honestly, most of the real problem was lazyness to reconfigure everything, and that’s why I published the question. But now I’m convinced that that’s the only way lol
Thanks for the help!

@astraeus yep, completely agree on the security issues, that is a mistake that should be fixed. But for the moment I confirmed that root is the only user, and every file and program in the instance can only be used by root (I just created a new user and tried to run the command with su -c but got a lot of permission denials and command not found)
If I could hide or disable my own sudo permissions that would save me a lot of work, but I’m starting to think that something like that doesn’t exist 🙁

@Oisteink in another comment (https://social.vivaldi.net/users/nirogu/statuses/111342629815373353) I explained why I’d prefer not to create another user, as it would require a lot of work to configure everything again for that command to work (it’s a big process). I was thinking of hiding my sudo permissions from the program or something like that, if possible, because many things in the instance are only configured to be used with the root user, even if they don’t require sudo. Anyway, I’m seeing that it might not be possible so creating a new user could be the only option 🙁

@Rustmilian yeah, already tried it. The problem is that all of the apps in the instance are only installed for the root user (e.g. python and all it’s libraries. So, when I use su -c all I get is a lot of command not found messages that would take a lot to solve. Besides I expect a lot more problems when the command needs access to some files and some processes (like a sql database) that would require me to do a lot of stuff to grant permissions to the new user. That would eventually work but given the work it requires I thought that some kind of “anti sudo” command or something like that could exist so I can still be the root user but pretend I am not a superadmin

Forgot to mention that creating a new user brings a lot of problems because of how that machine is configured and all the tools that would need to be added the new user’s permission. In theory it would eventually work after some time working on it, but I’d like to know if there’s a way to do it without creating users (or if it’s impossible, so I can just go on with that only option)
@linux

@astray yeah, that could be an option, but if more users exist in that machine then other processes might fail as that instance is part of a bigger cluster that has several processes running. It might not be a big deal, but checking that may still need some work. I’d prefer a way to do it without creating new users, if it exists
