You can use du -sh to figure out what’s using most of the space. Something along the line of:
sudo -i
du -sh /home /usr /var
du -sh /var/*
du -sh /var/log/*
# etc
If it’s one of your log files (likely), you can run something like tail -n 100 /var/log/[culprit] or tail -F /var/log/[culprit] to see what is being flooded in this log file exactly. Then you can try to fix it.
Oh actually if you are worried about vendor lock-in: Meshcentral is opensource. So even if they decide to try something stupid, a fork would be likely to happen.
I self-host Meshcentral. I haven’t seen any limitation at all. I don’t know if there are limitations when you use meshcentral.com instead of self-hosting.
Based on my tests on my family and friends, the main problem is tech support. Most geeks seem to assume other people want the same things than themselves (privacy, freedom, etc). Well, they don’t. They want a computer that just works.
Overall when using Linux, people actually don’t need much tech support, but they need it. My father put it really well by saying: “the best OS is the one of your neighbor.”
I apply few rules:
The deal with my family and friends is simple: you want tech support from me ? ok, then I’m going to pick your computer (usually old Lenovo Thinkpads bought on Ebay at ~300€) and I’m going to install Linux on it.
I’m not shy. I ask them if they want me to have remote access to their computer. If they accept, I install a Meshcentral agent. Thing is, on other OS, they are already spied on by Google, Microsoft, Apple, etc. And most people think “they have nothing to hide”. Therefore why should they worry more about a family member or a friend than some unknown big company ? Fun fact, I’ve been really surprised by how easily people do accept that I keep a remote access on their computer: even people that are not family ! Pretty much everybody has gladly agreed up to now. (and God knows I’ve been really clear that I can access their computer whenever I want).
I install the system for them and I make the major updates for them. Therefore, if I have remote access to the system, I pick the distribution I’m the most at ease with (Debian). They just don’t care what actually runs on their computers.
When they have a problem, they call me after 8pm. With remote access, most problems are solved in a matter of minutes. Usually, they call me a few times the first days, and then I never hear from them anymore until the next major update.
So far, everybody seems really happy with this deal. And for those wondering, I can see in Meshcentral they really do use those computers :-P
Also thanks to Wine/Proton. You have to give it to Valve : overall it works surprisingly well.
At first sight, it looks like it can be used with chroots thanks to systemd-nspawn (I haven’t tried it though)
I worked for a bank. When they decided to deploy Linux on their infrastructure, they chose RHEL and they have signed a big contract with RedHat for tech support.
Overall, they chose RedHat for the same reason they chose Microsoft before: tech support. They have >10000 engineers, and yet somehow they think they absolutely need tech support… They pay a lot for it. In my building, they even got a Microsoft engineer once a week on-site until Covid. I don’t know for the other people working for this bank, but I asked for Microsoft support only once in 2 years. In the end, their guy sent me back an email telling me “I’ve transmitted your question to the corresponding engineering team” and … diddlysquat.
Now to be fair, for paying customers, RHEL and Microsoft both ensure security updates for a really a long time. Red Hat pays a lot of people to backport security patches from upstream to previous versions. It allows companies like the bank I worked for to keep running completely crappy and obsolete software for an insane amount of time without having to worry too much about security vulnerabilities.
Anyway regarding RedHat contributions, a lot of them are subtle.
This list is far from exhaustive. I’m sure they have paid for a lot of other things you’re using daily without knowing it.
Red Hat. Probably Canonical too.
I know it for a fact since I worked for a bank that chose Red Hat and since I also know someone working for Red Hat.
