$ head -3 /var/log/pacman.log 
[2009-04-04 12:40] installed filesystem (2009.01-1)
[2009-04-04 12:40] installed expat (2.0.1-2)
[2009-04-04 12:40] installed dbus-core (1.2.4.4permissive-1)

I installed my Arch on Desktop in 2009 and it was just cloned from one disk to another through multitude of PCs, and sure, there were occasional troubles, like upgrade from SysV init to systemd, when KDE plasma 4 released, or the time, when I had to run a custom kernel and mesa which supported the AMD Vega 56 card ~month after release.

But nowadays, I didnt had a single breakage for several years, my RX6800 GPU was well supported 3 months after release, and most things just work... BTW I run arch also on my home server, in 6 years it had literally zero issues.

Ok wow! This is really impressive. I couldn't even run Windows or Debian or something like that for 15 years, yet you managed to do it with Arch. May I ask what was the main reason behind trying to keep this Arch installation for so long? Were you just to lazy to reinstall or are there other factors?

[–] [email protected] 7 points 5 months ago (1 children)

My arch install is from 2015. It just works, why should I reinstall?

@[email protected] mentioned cloning the drive and moving it to another computer. I imagine reinstalling would be easier at that point, that's why I asked.

[–] [email protected] 3 points 5 months ago

And reinstalling the packages, moving over all the configs, setting up the partitions and moving the data over? (Not in this order, of course)

Cloning a drive would just require you to plug both the old and new to the same machine, boot up (probably from a live image to avoid issues), running a command and waiting until it finishes. Then maybe fixing up the fstab and reinstalling the bootloader, but those are things you need to do to install the system anyways.

I think the reason you'd want to reinstall is to save time, or get a clean slate without any past config mistakes you've already forgotten about, which I've done for that very reason, especially since it was still my first, and less experienced, install.

Well not really, cloning is much easier than reinstalling and then configuring everything again...

I have LVM set up from the start, so usually I just copy the /boot partition to the new disk, and the rest is in a LVM volume group, so I just use pvmove from old disk to the new one, fix the bootloader and fstab UUIDs, and Im ready to reboot from new disk, while I didnt even left my running system, no live USB needed or anything. (Of course I messed it up a first few times, so had to fix from a live OS).

But once you know all the quirks, I can be up and ready on a new drive withing 20mins (depends mainly on the pvmove), with all the stuff preserved and set

That's really cool, how can I learn more about LVM and that kinda stuff?

[–] [email protected] 2 points 5 months ago* (last edited 5 months ago) (1 children)

There is many tutorials and how tos, this is quite nice one:

https://wiki.archlinux.org/title/LVM

BTW some filesystems like btrfs and ZFS already have a similar functionality built in...

Thanks :)

There were no real reasons to reinstall it, it works fine, occasionally had to purge some config files in home for some apps after major version changes, or edit them, but most work for years. I mean, my mplayer config is from 2009 and last edited 4 years ago...

How often do you do updates on your home server?

[–] [email protected] 2 points 5 months ago

once a month usually.
