Linux questions for sys admins on net
Hey everyone, I’m about to begin my sys and net administration courses but I have no prior Linux experience. Do you have any suggestions on which distribution to start with? Should I go straight for RedHat, Fedora, or Debian since those are common in the job postings? Also, should I try Ubuntu first or pick something simpler like Linux Mint? I’m also curious if it makes sense to learn Linux now before the classes start, especially since I might have to troubleshoot Windows systems later.
I began with Ubuntu Server. After getting comfortable, you can edit files or explore what feels right for you. Debian is quite alike, so changes are made swiftly. I don’t have experience with Fedora or Red Hat, but CentOS works well too—it’s similar to Red Hat and just requires knowing the available programs. With Ubuntu, apt-get handles updates and upgrades, while Red Hat uses yum. Each program has its own commands and syntax, but reading the docs helps.

Yesterday my friend created a video showing his Arch Linux system booting in just two seconds. He mentioned that using systemd improves performance since the loading happens in parallel. How can someone set up systemd, or is this feature only available on certain distributions?
I'd begin studying the distribution they'll cover in class. Once you grasp it and feel confident, switching distributions will come naturally since you already know the fundamentals. Avoid diving into systemD versus init scripts—it's a complex topic you won't escape.
This approach aligns with common practices, as many users opt for systemd instead of openrc by default. Stability is indeed a key consideration, and openrc is often praised for its reliability. It’s understandable that this topic can feel broad for those new to Linux.
Systemd contrasts sharply with what Linux represents. As mentioned, avoid diving into that topic publicly unless you're comfortable. Let me know if you'd like further discussion.
To get as near Redhat as possible, consider using CentOS or Scientific Linux, both built on RHEL. I don’t have a perfect solution since you’re using many of them, so you might want to try everything or concentrate on the system you use most in class.
