I am running a homeserver and have documented how to setup a homeserver using best practices, official documentation (arch wiki) etc to have as little as regular maintenance as possible and as little as notifications, only ones that matter. It should just do its thing. And very, very easy to restore (BTRFS).
After summer I would like to switch OS from Manjaro, which I only chose because out-of-the-box it does a lot right already, but obviously with lots of things a server doesn’t need, to OpenSUSE Aeon. I have read the wiki mostly already, and it made me very happy.
However, a few questions remain, just to see if I understand things. Hope the experts have some time to look at the following questions:
Does it use bash or zsh by default?
Does Aeon support something like a sysRq key, Suse seems to have it. Allowing one to gracefully reboot or power-off the system if the OS freezes. Is there a guide how to enable it for Aeon?
Cronie and systemd are used by default in Tumbleweed, I suppose also in Aeon?
I consider the following list of tools to be OS system tools, essential to my server to work properly. Am I correct thinking I should install these tools via transactional updates? Would that be considered a best-practice for these tools specifically?
Wireguard is part of Linux Kernel, but this package is quite essential to be able to use Wireguard properly.
btrbk and mbuffer
btrbk is the de facto system tool for BTRFS backups. It does the snapshotting, backing up to different local or networked (SSH) or USB locations, archiving backups, setting retention policies per target etc. Since it works directly with btrfs filesystem, I would also use it to delete snapshots automatically (to adhere to my retention policy).
mbuffer is optionally used to provide a progress indication.
rsync, grsync and nocache, rsync
to securily copy files and do so optionally without cache. Optionally also the GUI version of rsyn.
smartmontools including smartd systemd service
to get S.M.A.R.T. data from drives and also warn when thresholds have been reached.
to read/set drive firmware settings
to unionize multiple drives, without raid, just simple user-level unionizing.
to create parity drives, especially in combination with MergerFS.
Essential to ensure all C-levels of CPU (C-10) are used when idle and all hardware that can go into a lower state of power consumption, will do that. A homeserver is idle most of the time, saving power here is essential for an efficient server.
The simplest way on Arch-based and Debian/Ubuntu based distros to allow the OS to send email notifications by adding your public SMTP server and set your default address in /etc/aliases. Not sure if OpenSUSE has its own solution. I simply followed Arch Wiki here, which is very simple to setup.
I always replace Gedit (Gnome Text Editor) with Pluma Text Editor. Very used to Pluma now (Xed is nearly identical so also an option if Pluma is not properly supported).
My main question here: I suppose Aeon comes with Gedit by default, not installed as Flatpak. If I want to replace it with Pluma, should I install it in the same way Gedit is installed? Or via Flatpak?
