screnshot, current create new partition
Advantages of the "Linux systems only" option using Btrfs instead of ext4:
* Always on checksumming for metadata and data - Flash is notoriously of
variable quality, often the first indication of imminent failure are small
transient corruptions that get progressively worse. Btrfs not only detects such
corruption but will issue an I/O Error for blocks that fail integrity checking,
preventing replication of damaged files.
* Native compression - separately or as part of this proposed change, also
enable minimal (performant) compression via compress=zstd:1 mount option by
default. This will improve performance, since removable flash devices are
pretty slow. It will also improve performance on (spinning) hard drives. An
extra benefit is it substantially reduces writes and thus wear on flash. And
effectively greater storage capacity is likewise a bonus. Kernel 4.14+ supports
zstd.
Prior efforts:
* (open)SUSE defaults to Btrfs for a long time now, for / and /home
* Fedora 33 Workstation, and all desktop spins default to Btrfs.
* systemd-homed defaults to Btrfs beginning with v247.
To do:
* Support FS_IOC_SETFSLABEL so we can change file system labels while the fs is
mounted. Ideally get ext4 and XFS to support this ioctl as well.
* Btrfs subpage support, so file system are portable across arches using a page
size other than the common 4KiB. (Read only support has happened, and
read-write support should land in 5.14.)
* Partition -> Check -> Check and Repair probably should only do 'btrfs check
--readonly' and report any issues.
