# With kernels 5.15 and newer be cautious of adding the option space_cache
# to the btrfs mount options. The default in 5.15 changed to space_cache=v2.
# If space_cache or space_cache=v1 are specified, it may fail to remount.
#
# btrfs_swap options are used when a swapfile is chosen with a btrfs root
# the options are applied to the subvolume which holds the swap partition
mountOptions:
default: defaults,noatime
btrfs: defaults,noatime,autodefrag,compress=zstd
btrfs_swap: defaults,noatime
# Mount options to use for the EFI System Partition. If not defined, the
# *mountOptions* for *vfat* are used, or if that is not set either,
