I am not in measure to comment about the righteous of this code snippet, also I am not a KDE or Plasma user, but I imagined a simple experiment good to be made in XFCE as typical user:

I am pretty sure that while using Ubuntu, you will be asked first time only for the password, but while using Slackware you are asked for password every time. Really inconvenient, though.

And looks like there is at least a fundamental difference between Ubuntu and Slackware. The difference in behavior is because of the SystemD usage?

how long have you used Ubuntu?

No, I do not think the difference is generated by the SystemD usage.

Rather, I will consider that is about the Linux-PAM usage.

Around 5 years. And one of the reasons I preferred in the end the Slackware is because Ubuntu has no root account, at least not by default.

And doing system wide commands over sudo and sudoedit is rather inconvenient, in my humble opinion.

But I will say it again: Ubuntu does not ask me for the password every time.

As an aside, geany is good enough for me, although the syntax highlighting of kate may be slightly better in some cases (I don't remember exactly, as I haven't used kate since a very long time).

Also, to avoid polluting a regular user's home I become root with su - whenever I want to use a text editor as root.

You managed to use kate over "su" under Plasma?

No, that was KDE4. But TBH I don't remember having ever used kate as root anyway, so forget it, and sorry for the off topic

Personally, I am a legit user of the Sublime Text Editor, brilliant editor for programming. And I appreciate it well.

The main reason for me to favor Kate instead, is because apparently Kate is capable to handle visible more files opened simultaneous, for the same memory consumption.

It is not off topic, Didier.

And in the KDE4 nothing stops you to use Kate or KWrite as you like as root. Sure, not over "su", as @LuckyCyborg legit wondered.

But using "kdesu" instead, you will manage that well.

I agree, it's easy to use kdesu, or create a launcher that will use kdesu, gslapt use kdesu for exemple.

However, I think you can mark the thread as solved. He's not joking, he's rather dead off seriously instead.

I understand that is unbelievable for after 20 years usage of Slackware to see the mighty root having its own actions limited, "for his own protection".

I seen some calling that "Windows like ideas of trying to protect users from themselves", you can also (legit?) call that "babysitting", however looks like Slackware does not trust its users anymore and jumped (or is ready to jump) in the "babysitting" bandwagon, even it may or may not been prepared to proper doing it.

So, enjoy your favorite Pampers and be happy!

Meanwhile, under Eric's Plasma you cannot use "kdesu" to launch KWrite or Kate, because they will complain about the root usage.

Ironically, you are still able to launch GParted via "kdesu" and mess as your heart like with the partitions or to launch the GSlapt and to remove half of the operating system, just only doing some clicks.

Heck! You can even open a root Konsole via "kdesu", and to give to OS a final order like
BUT NOPE, the Kate is more dangerous.

Yeah, on that POV I agree.

Do not worry I always use what I want, as I want.

You forget about the soma, that little audio player.

I guess that for some very serious reasons, they are afraid that listening to BBC Radio while having root powers, could make you to issue "the final order" ...
