Installation date

Just a quick question here,

Does anyone know how to determine the actual date and time that one
originally installed an operating system?

I installed openSUSE 12.2 (clean install) sometime back in August or
September. I would like to record the actual date.

My /var folder shows adate of August 25, 2012when I type ls-l. But I
don’t know if that is the actual creation date, and if it is, was it the
date the folder was created at the factory before I installed 12.2, or
is it the date I installed 12.2?

Is there a better way to figure this out?

Some of the oldest files in “/var/log/YaST2” will be install logs. Look at the oldest y2log-* and there will probably be other files with a similar time/date.

I’m not sure about install from a live KDE or Gnome, as some of the logs might be for preparing the live system.

Ok, that is great. I found out what I needed to know on the installation
of my upgrade.

Now here is another question - is there a way to find out the date on
which I partitioned the hard drive on my laptop? I set up new partitions
on it when I first got it before installing my operating systemso that I
could run dual boot with Windows 7 and openSUSE.

I don’t know
And I doubt it

If your filesystem is ext4[3,2] it is simple to find out when a filesystem was created.

tune2fs -l /dev/sdaX | grep "Filesystem created"

…where X is the number of the partition. That is also the simplest way to find out the date of installation, because before installation the partition will mostly be formatted.

Or the timestamp of the first line in the older /var/log/messages*gz
file, assuming it has not rotated out.

Or the timestamp of the file /etc/SuSE-release

There are several places, check them all, and if they match, you got it :slight_smile:

I doubt that.

ls -l /etc/SuSE-release
-rw-r--r-- 1 root root 56 29. Aug 2012  /etc/SuSE-release

And I installed this version on the current running system at 2012-11-16

tune2fs -l /dev/sda2 | grep "Filesystem created"
Filesystem created:       Fri Nov 16 12:59:21 2012

The timestamp of /etc/SuSE-release is even earlier than the release date.
