faster operation where is that stated? Depending on how old your
"distro" is, btrfs can be slower. (apt will be slow, dpkg sync calls)
I'm looking at is for it's native compression, and the possibility of
improved reliability over ext4 in systems where power get's yanked.
Right now, all "buster-iot" images are btrfs by default on the weekly builds..

3.8.x had it enabled:
CONFIG_BTRFS_FS=y
CONFIG_BTRFS_FS_POSIX_ACL=y
# CONFIG_BTRFS_FS_CHECK_INTEGRITY is not set

Nope.. There's a few more things you have to do manually...
Just grab a newer weekly snapshot, don't waste time trying to directly
convert that old image your running.
