#
# LOADER_*_SUPPORT variables are used to subset the boot loader in the various
# configurations each platform supports. These are typically used to omit broken
# options, or to size optimize for space constrained instances. These are set in
# loader Makefiles (which include loader.mk) to control which subset of features
# are enabled. These cannot generally be set in src.conf since that would affect
# all loaders, but also not all loaders are setup for overrides like that and
# not all combinations of the following have been tested or even work. Sometimes
# non-default values won't work due to buggy support for that component being
# optional.
#
# LOADER_BZIP2_SUPPORT	Add support for bzip2 compressed files
# LOADER_CD9660_SUPPORT	Add support for iso9660 filesystems
# LOADER_DISK_SUPPORT	Adds support for disks and mounting filesystems on it
# LOADER_EXT2FS_SUPPORT	Add support for ext2 Linux filesystems
# LOADER_GPT_SUPPORT	Add support for GPT partitions
# LOADER_GZIP_SUPPORT	Add support for gzip compressed files
# LOADER_INSTALL_SUPPORT Add support for booting off of installl ISOs
# LOADER_MBR_SUPPORT	Add support for MBR partitions
# LOADER_MSDOS_SUPPORT	Add support for FAT filesystems
# LOADER_NET_SUPPORT	Adds networking support (useless w/o net drivers sometimes)
# LOADER_NFS_SUPPORT	Add NFS support
# LOADER_TFTP_SUPPORT	Add TFTP support
# LOADER_UFS_SUPPORT	Add support for UFS filesystems
# LOADER_ZFS_SUPPORT	Add support for ZFS filesystems
