1
00:00:06,719 --> 00:00:10,029
Let me reboot so that we
can activate the Grub bootloader menu.

2
00:00:12,109 --> 00:00:14,470
Press E to
get into it.

3
00:00:15,130 --> 00:00:21,289
Then the end of the line that
loads Linux. I'm removing RHDB and quiet

4
00:00:21,289 --> 00:00:27,449
and I'm using systemd Unit is emergency
dot target. That's the most minimal way.

5
00:00:27,969 --> 00:00:31,440
Don't press enter. Use Control
X to start with this parameter.

6
00:00:33,640 --> 00:00:40,039
So as this is using Azure login on a
Red Hat system, I need to enter the root password

7
00:00:40,039 --> 00:00:46,439
and then I can use systemctl list units to
show all the different systemd units that are available.

8
00:00:47,460 --> 00:00:51,030
This is shown screen by screen.
Use the spacebar to move forward. And

9
00:00:51,030 --> 00:00:54,600
we can see a total of
98 units. Units have been loaded.

10
00:00:55,020 --> 00:00:58,885
Most of them are
related to devices, and there's

11
00:00:58,885 --> 00:01:02,750
only a very minimal
number of services available.

12
00:01:03,530 --> 00:01:06,090
Only essential services
are available here.

13
00:01:07,010 --> 00:01:11,836
Now I can use systemctl Start
Rescue unit, Rescue Target normally to move

14
00:01:11,836 --> 00:01:16,663
from the emergency target to the
rescue target. And that should give a

15
00:01:16,663 --> 00:01:21,489
little bit more. And as you
can see, more stuff is happening.

16
00:01:22,069 --> 00:01:28,946
So I'm entering my password and then
systemctl list units again is showing all of

17
00:01:28,946 --> 00:01:35,823
these units and you can see that
more is available. The mounts are available. Now

18
00:01:35,823 --> 00:01:42,700
you have a few more services. You
have a pretty nice basic operating system.

19
00:01:43,560 --> 00:01:48,140
Now. It's kind of funny that we
have fewer units than in Emergency targets, but

20
00:01:48,140 --> 00:01:52,719
that is because of the way how
in Emergency Target hardware devices are addressed.

21
00:01:53,459 --> 00:01:59,390
Emergency Target is doing that in a way that makes it
more likely that you get access to all of your hardware.

22
00:01:59,930 --> 00:02:03,450
And that is how you do
it. And at the end, don't

23
00:02:03,450 --> 00:02:06,969
forget to type reboot to
boot back into normal operational mode.
