I'm an idiot (arm)

EDIT: Putting this at the top because not everyone is seeing what I actually need. I can unpack the rar archive just fine. What I can’t do (on arm) is add to/update the files in the rar archive. I have unrar already installed. What I can’t install is the rar package to create/update rar archives....

As a last resort you could install docker from apt, build an image from a distro has rar in its arm repos, then run containers ephemerallly, mounting your work dir into the container where rar runs. Try the suggested methods of getting a binary first. 😅


<span style="color:#323232;">docker run --rm -v /your/work/dir:/destination/in/container your_image rar ...

Yup, moving away from rar would probably be best.

Upgrade vs Reinstall

I’m a generalist SysAdmin. I use Linux when necessary or convenient. I find that when I need to upgrade a specific solution it’s often easier to just spin up an entirely new instance and start from scratch. Is this normal or am I doing it wrong? For instance, this morning I’m looking at a Linux VM whose only task is to run...

It depends on the type of machine you’re talking about. Pet machines, bare metal or VMs, such as workstations, desktops, laptops are generally upgraded because it takes a while to re-setup everything. Cattle machines such as servers are generally recreated. With that said, creation of such machines typically involves some sort of automation that does the work for you. Setup scripts are the very basic, however configuration as code systems such as Ansible, SaltStack are much preferable. So if I had a VM that runs acme.sh, I’d write an Ansible runbook that creates it from a vanilla OS installation. I stop here for my own infrastructure. When we do this in cloud environments where we need to spin up more than one such VM and quickly, we’d have the OS install and Ansible run in a Jenkins job which builds a VM image that’s pushed to the cloud. Then we spin up ready acme.sh VMs from that image which takes seconds.
