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.

Help on BTRFS setup (self.linux)

submitted 10 months ago by actual_patience to c/[email protected]

17 comments fedilink hide all child comments

I'm attempting a new install. I want to use btrfs with swapfile.

Do I need to disable compression on my swap subvolume?

Is there anything else I should keep in mind for fstab if I want to, say, not keep track of my Downloads folder when snapshotting?

Here is my fstab:

LABEL=arch@btrfs        /               btrfs           rw,relatime,discard=async,space_cache=v2,subvolid=256,subvol=>

LABEL=arch@btrfs        /home           btrfs           rw,relatime,discard=async,space_cache=v2,subvolid=257,subvol=>

LABEL=arch@btrfs        /var/cache/pacman/pkg   btrfs           rw,relatime,discard=async,space_cache=v2,subvolid=259>

LABEL=arch@btrfs        /var/log        btrfs           rw,relatime,discard=async,space_cache=v2,subvolid=258,subvol=>

LABEL=arch@btrfs        /.snapshots     btrfs           rw,relatime,discard=async,space_cache=v2,subvolid=260,subvol=>

LABEL=arch@btrfs        /swap           btrfs           rw,relatime,discard=async,space_cache=v2,subvolid=263,subvol=>

LABEL=efi@fat32         /efi            vfat            rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=asci>

/swap/swapfile          none            swap            defaults        0 0

Are you sure you can use a swap file with btrfs? I did not think you could do that. Maybe I was on old software last time I tried.

It's been supported for several years now
