Practical questions about disk partitioning, moving the /home directory and shrinking the / system directory.

[Bas G. Roufs]

Hey dear Nils and others.

Yesterday, I carried out some tests in the realm of disks, partions and
software. Updates seemingly function well. Apparently no broken packages.
Before closing the last working session in the recovery mode, I DID manage
to....

+ mount sda;

+ identify mount points of sda3, sda 5 and one more partion;

+ find «home new» at sda5.

All this gonna help to get fixed the system today.

Exactly.

I get this idea. I understand everything you write here. I can do so. But
one important question remains.....

Run konsole and become root with the command

I get this idea. But what about the superuser password when running the
live version of Kubuntu 24.04 LTS?

This idea I get. However, how to deal with the password issue? Is there a
way to get around it?

Now check that sda is your 1TB SSD with

I get this one.

Good point. Did not do so yesterday in the recovery mode session.

I get it..

If it doesn't exist, create a new empty home folder:

I get this too.

Tests yesterday in the recovery mode delivered this result.

If you really find the home-new folder instead of the bas folder, move the

I know, the folder /home-new/ exist. However, not sure yet about
/home-new/bas/.

I tend to do so anyway, because the «home-ori» folder at sda3 is more up to
date then «home-new» at sda5.

Also this check I still need to carry out from the Ventoy live USB?

I am happy to do so after getting clarity about the super user password
issue.

Thanks, yours,
Bas.
