Let me reboot so that we can activate the Grub bootloader menu.
Press E to get into it.
Then the end of the line that loads Linux. I'm removing RHDB and quiet
and I'm using systemd Unit is emergency dot target. That's the most minimal way.
Don't press enter. Use Control X to start with this parameter.
So as this is using Azure login on a Red Hat system, I need to enter the root password
and then I can use systemctl list units to show all the different systemd units that are available.
This is shown screen by screen. Use the spacebar to move forward. And
we can see a total of 98 units. Units have been loaded.
Most of them are related to devices, and there's
only a very minimal number of services available.
Only essential services are available here.
Now I can use systemctl Start Rescue unit, Rescue Target normally to move
from the emergency target to the rescue target. And that should give a
little bit more. And as you can see, more stuff is happening.
So I'm entering my password and then systemctl list units again is showing all of
these units and you can see that more is available. The mounts are available. Now
you have a few more services. You have a pretty nice basic operating system.
Now. It's kind of funny that we have fewer units than in Emergency targets, but
that is because of the way how in Emergency Target hardware devices are addressed.
Emergency Target is doing that in a way that makes it more likely that you get access to all of your hardware.
And that is how you do it. And at the end, don't
forget to type reboot to boot back into normal operational mode.
