Arch Linux

Well you're being far more in-depth than me. I just run pacman -Syu periodically.

you can automate some parts of that away or can be combined
most AUR helper will basically invoke pacman -Syu internally before actually upgrading any AUR package (as otherwise this can lead to issues)
yay in particular can just be called via yay (no arguments) which is an alias of yay -Syu

Point 3: reflector.timer comes with reflector now and runs weekly by default, you need to configure and enable it though
https://wiki.archlinux.org/title/Reflector#systemd_timer

Point 4: you can restrict the journal size to much smaller than it is by default (10% of the partition size OR maximum 4 GB): https://wiki.archlinux.org/title/Systemd/Journal#Journal_size_limit
or alternativly set MaxRetentionSec to 2419200 seconds (4 weeks)

Point 5: can be done via pacman hook automatically after every upgrade
example: https://aur.archlinux.org/packages/pacman-cleanup-hook

there are also many other useful pacman hooks which tell you if there are any orphans or if AUR packages need to be rebuild or there is a hook which reload kernel modules after a kernel upgrade (which otherwise would warrant a reboot unless you are ready for the issues of many unloaded kernel modules)

I don't even have backups except git repos for my code and config. :)

I just run 'paru'.

Looks interesting and comprehensive though, a few things I should probably implement.

I just backup my stuff - dot files, docs, etc regularly. My whole system is disposable - meaning I can reformat anytime (I do it regularly).

You are way more involved than I am. I usually just do pacman -Syu and yay -Syua every couple of days and then pacman -Sc about once a month to clean out the package cache.

Just so that you have an additional data point, here's how I do it.

I run a backup first, using borg-backup. I used rsync in the past, then rsnapshot and now borg since it allows for compressed incremental backups, diffing on the "chunk" level, meaning I won't backup the entirety of a modified file again and safe a lot of space.

I used yay before, but like you I didn't want to go into it blindly and do some modicum of sanity-checking the PKGBUILD for changes beforehand. Since it wasn't obvious on what would be the best way of using yay for doing this, I asked around on the ArchLinux Forum, and ultimately decided to try one of the simpler tools suggested in the Arch Wiki, aurutils.

After setting it up (the author helped me migrate), I now use it as follows:

• aur repo --upgrades: Searches for new versions of aur packages and displays them
• aur sync --upgrades --no-build: Performs a git-pull under ~/.cache/aurutils/sync and opens vifm so that I can look at a diff of the PKGBUILD and all the other changes in the affected directory.
• aur sync --upgrades --no-view: Builds the package. It is now available as part of the custom (local) repository used only for aur packages, but hasn't been upgraded yet. That is, a package.tar.gz or whatever has been created and put into ~/.cache/aurutils/sync/, where the PKGBUILD resides as well
• sudo pacman -Syu: Upgrades all packages from all repositories, including the ones from the custom repository

I won't argue pro or against one aur helper or the other, but I feel like I have a little more insight about what happens under the hood since I made the switch. That being said, in the very beginning, I managed aur packages manually. This works also, but at some point became too tedious for my taste. I am happy with the semi-automatic approach I am using now.

I have one suggestion and that is to save yourself some time.

Auto-Backups, snapper + snap-pac, a hook that runs reflector (or alternatives) on its own, another one for flatpaks. I'm also not sure whether you actually need to run yay independent of pacman. I never did with yay or paru.

You could eliminate like half of that process I think, but please correct me if I'm missing something.

LMAO.

You can update flatpaks by running flatpak update.

You can automate updating the mirrorlist by enabling reflector.service or reflector.timer.

How often do you do all this?
How long does it take?

Maybe it is too late because of your filesystem choice but btrfs snapshots delievers enough security if something goes wrong. Rsync seems like a little bit overhead for updating only There is even a pacman hook that makes pre and post snapshots of your filesystem with snapper. Tldr: most of your steps can be automated with pacman hooks. But if you like it this way its fine

So yeah. If I needed a 12 step process to update my system it would still run kernel 4 :D (I'm lying of course) but i really don't do as much as you and I don't do more than necessary manually. Basically I run 2 commands to update:

1. update which runs the update process more below.
2. clean which removes orphans and cleans the cache

So update is the alias where the magic happens and it does the following:

1. It runs sudo pacman -Syu checking with the Informant hook if there are any unread news, if so it stops the update. Otherwise it just runs through it.
2. Then it runs pacdiff to check if any config files changed (I ran into an issue with that before where I didn't check properly and suddenly couldn't login anymore.
3. Then, if flatpak is installed it will also update all flatpaks.

So my only manual intervention is "accepting" the news if there are any. Accepting the updates. And (of necessary) merging the pacnews. This way I have kept a fresh and stable system for a couple of years now.

I have an alias in bashrc called upgrade. It runs reflector looking for the fastest of the newest 10 near me. Then it upgrades the keyring, then yay -syu and then paccache -r.

I have the journal limited to 100mb so I don't ever bother cleaning house on that.

I probably don't review pacman logs as often as I should, but stuff rarely breaks and is normally pretty easy for me to figure out what when it does.

Some suggestions:

Step 1:

rsync has a -x flag that stops it from crossing filesystem boundaries. I find it quite useful so that I don't have to manually exclude all these directories with mounted pseudo filesystems and whatnot. Alternatively, you can also do a second mount of the filesystem you want to backup in a more convenient location than /, and run your rsync from there.

If you want to be fancy, you can also use rsync's --link-dest option to maintain different versions of your backup, so that you can go a bit further back in time. Using this option rsync creates hardlinks for files that are unchanged between the current backup and the previous one, and you can have multiple backups without much storage overhead and while still keeping the backup incremental and speedy.

Step 3:

Reflector comes with a weekly timer preinstalled. You can enable it with systemctl enable reflector.timer and then just edit the config file to your preferred settings.

Alternatively, it also has a service that you can enable so that it runs at boot time, but that doesn't work for one of my systems that is using wifi. For some reason it runs before the network is truly available and returns an error. On my ethernet connected system, I don't have that issue.

Step 4:

Instead of vacuuming your journal manually, you can also set limits in /etc/systemd/journald.conf. I just set SystemMaxUse to something sensible like 512M, so I don't ever have to worry about my journal overflowing my disk.

Step 5:

I just automate the paccache stuff with a simple cron.weekly entry. You may also want to look into where yay caches its packages.
