last simply shows who has recently used certain files and | or logged in-out.

More reliable result may be obtained by asking tune2fs "When my file system was created?" with the command:

sudo tune2fs -l /dev/sdXnn | grep -i created

where Xnn is a1, a2,.. a99, b1, b2,.. b99, c1, c2,..

It works only when a filesystem, once created, has never been moved or otherwise re-created.

I frequently move my systems between various partitions, using backup-restore with FSArchiver. During restore, it allows to create a filesystem in destination partition from scratch.

I have a few Arch systems installed in 2008. When I backup and then restore them, their original creation date is lost - it gets the "restore date" value.

    Mine are almost the same:

    What @just said.

    Eventhough wtmp in my case is quite close it's still not reliable as your wtmp could have been rotated (or changed otherwise) at some point.

    Best way is to simply get your root fs:

    $ mount | grep "on / "
/dev/nvme0n1p3 on / type ext4 (rw,relatime,errors=remount-ro)

    and find out when it was created:

    $ sudo tune2fs -l /dev/nvme0n1p3 | grep "Filesystem created:"
Filesystem created:       Wed Jul 17 00:49:01 2019
    $ sudo tune2fs -l /dev/sdb16 | grep -i created
Filesystem created:       Fri Dec 22 21:33:24 2017

    Maybe I'll check my laptop later, should be a bit older. But both systems have been reinstalled once (in one case to remove Windows completely, in the other to fix the Windows installation 🙂 )

    You can just use eopkg hs and scroll to the bottom with PG Down to get the install date, but the method just mentioned is more fancy and distro-agnostic.

    Here's my output.

        Junglist You can just use eopkg hs and scroll to the bottom with PG Down

            If mine is more than a month old I must have been busy and haven't had time to tinker and break things..

            I have several systems running Solus but the oldest existing install is:
            Filesystem created: Mon Mar 12 15:58:21 2018

            January 2018 on the main laptop (Budgie), june 2018 on the wife's laptop (Budgie again) and a couple of weeks ago a Plasma install on the Big One (an old Asus ROG.....1.2kg of powerbrick alone)

            That was a difficult month, Oct 2019. Gnome 3.34 had just been recently released on Solus and it was not the smoothest upgrade. It did smooth things out later (3.34 eventually became my favorite release at the time), but it was a good 2 weeks of hell, jumping to unstable, and having my hybrid laptop graphics trying to eat and freeze itself I ended up having to wipe it and start fresh! But before I did I tested out and helped out as much as I could. Thankfully, to end a rant that no one needed, the Gnome 3.36 upgrade this time around was essentially problemless on my end, so kudos to all the users that help and patch and curse and sweat while fixing Gnome 🤣
