From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I can't edit /etc/default/grub (pawb.social)

I'm trying to update my grub boot order back to booting the first option instead of the second, so I run sudo nano /etc/default/grub, but it brings up this, which is not the file I want to edit.

I'm on fedora 38

On shared systems with untrusted users, you're right. On your own system when you already have full admin rights, sudo nano is fine and doesn't have any security implications that I'm aware of.

I agree with the general sentiment. Thank you for mentioning that!

Though, the use of sudo nano might still pose a risk if any software found on the system is either vulnerable/exploitable, not trusted, or simply exploitative. In that case, like what's achieved through sandboxing i.e. not allow the software to go beyond their intended scope, it makes sense to put a limit on the capabilities of the software. And to that effect, the use of sudoedit still offers merit over sudo nano.

Though, if the user doesn't (already) rely on bubblejail, firejail, Flatpak etc for what they offer in sandboxing. And/or if said user simply doesn't care for the principle of least privilege, then the use of sudo nano is perfectly valid.

This isn’t a scenario I’m familiar with. How can I learn more?
