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.

File System Benefits (lemm.ee)

Potentialy dumb question here, is there any benefit to using btrfs on a non system disk? I'm fairly ignorant on file systems, asfaik btrfs largest benefit is snapshotting, not sure of anyothers.

I usually just stick to the standard file system to any OS.

So for Linux that would be ext4.

For external drives i use either FAT32 (the ol' reliable) or exFAT (the fastest for dealing with large files when you set the max allocation unit size AKA 32MB).

It's worth noting that the default file system varies by distro - there is no 'Linux' default. For example, RHEL et al use XFS as the default.

I thought RHEL is going with ext4 or btrfs these days. I know Fedora is on btrfs, while Debian & Ubuntu is on ext4.

RHEL is going hard on XFS, they've even completely removed BTRFS support from their kernel - they don't have any in-house development competency in it after all. It's somewhat understandable in that regard, since otherwise they wouldn't necessarily be able to offer filesystem-level support to their paying customers.

Though it is a little bit amusing, seeing as Fedora - the RHEL upstream - uses BTRFS as their default filesystem.

If there is one thing one can learn from the Linux community at large is how to agree on absolutely nothing and still be friends (mostly, that is. As long as Linus isn't involved. Then the gloves are off. Who dared to put rust in the kernel?!)

Is Red Hat the next canonical?

[–] [email protected] 7 points 10 months ago

Fedora’s gone the btrfs route, RHEL has all but given up on btrfs, pushing xfs

make menuconfig says:

Ext2 is a standard Linux file system for hard disks.

And this for ext4:

This is the next generation of the ext3 filesystem.

But defaly indeed is ext4.

ext4 is literally just the latest version of the ext filesystem (AKA it has the most funcionality).

If you REALLY wanted MAX speed, you could make your system drive ext2, but you would lose some metadata, drive info & management tools.

It says it is "a" standard file system - not "the" standard. Very different things.
