# When creating fstab entries for a filesystem, this module
# uses the options for the filesystem type to write to the
# options field of the file.

# Mount options to use for all filesystems. If a specific filesystem
# is listed here, use those options, otherwise use the *default*
# options from this mapping.
#
# 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
#
# The settings shown here apply only the btrfs defaults; these
# are generally the right ones. Commented-out lines show other
# options wich **might** be applicable for specific situations.

# 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,
# *default* from *mountOptions*.

# If a filesystem is on an SSD, add the following options. If a specific
# filesystem is listed here, use those options, otherwise no additional
# options are set (i.e. there is no *default* like in *mountOptions*).
#
# This example configuration applies the *discard* option to most
# common filesystems on an SSD. This may not be the right option
# for your distribution. If you use a systemd timer to trim the
# SSD, it may interfere with the *discard* option. Opinions vary
# as to whether *discard* is worth the effort -- it depends on
# the usage pattern of the disk as well.

# ssdExtraMountOptions:
# ext4: discard
# jfs: discard
# xfs: discard
# swap: discard
# btrfs: discard,compress=lzo
#
# The standard configuration applies asynchronous discard support and ssd optimizations to btrfs
# and does nothing for other filesystems.

# For Debian and Debian-based distributions, change the above line to:

# Options for handling /tmp in /etc/fstab
# Currently default (required) and ssd are supported
# The corresponding string can contain the following variables:
# tmpfs: true or tmpfs: false to either mount /tmp as tmpfs or not
# options: "<mount options>"
#
# Example:
#tmpOptions:
# default:
# tmpfs: false
# options: ""
# ssd:
# tmpfs: true
# options: "defaults,noatime,mode=1777"
#
tmpOptions:
