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.

How do programs that measure available space like 'lsblk', 'df', 'zfs list' etc see hardlinks and estimate disk space.

If I am trying to manage disk space, does the file system correctly display disk space (for example a zfs list)? Or does it think that I have duplicate files/directories because it can't tell what is a hardlink?

Also, during move operations, zfs dataset migrations, etc... does the hardlinked file continue tracking where the original is? I know it is almost impossible at a system level to discern which is the original.

@cyclohexane Is there any risk for me to try installing Linux on my MacBook (intel) and are there specific distros that run better on a macbook?

[–] [email protected] 3 points 8 months ago

Check compatibility first. Some of em need a binary blob network driver that certain distros don’t ship by default. But yeah you can run Linux on Macs pretty good. What mb do you have and I can give better input?

How do I enable DNS over HTTPS or DNS over TLS for all connections in NetworkManager in Debian 12?

It is easy to configure custom DNS servers for all connections via a new .conf file in /etc/NetworkManager/conf.d with a servers=8.8.8.8 entry in the [global-dns-domain-*] section.

How can I configure NetworkManager to use DNS over HTTPS or DNS over TLS via a conf file?

NetworkManager doesn't support DoH, DoT or other recent protocols like DoQ and DoH3. You'll need to set up a local DNS resolver / proxy which can handle those protocols. You could use dnsproxy for this. Once you set it up, you can just use "127.0.0.1" as your DNS server in NetworkManager.

Btw, if possible I'd recommend sticking to DoH3 (DNS-over-HTTP/3) or DoQ (DNS-over-QUIC) - they perform better than DoT and vanilla DoH, and are more reliable as well.
