As of Syslinux 6.03, the extlinux command line installer supports 512 bytes per sector.
Please contact The Syslinux Project if the extlinux command line installer fails in any way in the supported filesystems or if the boot process fails after installing the bootloader.
For the available command line options, see Install.
Initial support for Btrfs was introduced in Syslinux 4.06. Several improvements and fixes were added in later versions. Syslinux 6.03 (or later) is recommended.
As of Syslinux 6.03, the compression and/or encryption features of Btrfs volumes are not supported. In other words, Syslinux cannot find (configuration / kernel / initrd) files if the boot filesystem is compressed and/or encrypted.
Additional boot parameters might be needed so to specify Btrfs subvolume IDs.
As of Syslinux 6.03, "pure 64-bits", compression and/or encryption are not supported.
Initial support for NTFS was introduced in Syslinux 4.06. Several improvements and fixes were added in later versions. Syslinux 6.03 (or later) is recommended.
Note: As of Syslinux 6.03, Syslinux supports NTFS volumes with Cluster (aka "Allocation Unit") size equal or smaller than 4096 bytes.
4096 Bytes (or less) per "Allocation Unit" (aka Cluster). Each Cluster can be 4KiB or smaller. For 512 Bytes per sector → either 8 / 4 / 2 / 1 Sectors per Cluster. For 4096 Bytes per sector → 1 Sector per Cluster.
A Cluster size of 4096 bytes is usually the default and the recommended value.

As of Syslinux 6.03, EXTLINUX does not support symlinks on NTFS volumes.
Syslinux 6.03 adds support for UFS/FFS in little-endian architectures (x86 and x86-64). UFS1 and UFS2 are both supported.
The author of UFS/FFS, Kirk McKusick, said about the name:
The code is broken into two parts, the part that handles naming (UFS where the U stands for Unix), and the part that handles disk layout (FFS where the F stands for Fast). When the two parts are put together they are called UFS/FFS or more commonly just UFS.
- The following steps were initially only made under a GNU/Linux environment. Therefore, functionality might vary on other systems.
- Dependency: ufsutils (UFS filesystems utilities) or equivalent.
- To add Write support on UFS to Linux, a kernel with the option CONFIG_UFS_FS_WRITE enabled is needed, or at least configured as a module. To the latter case, load the module "ufs.ko" with modprobe (probably located at "/lib/modules/").
- Enable UFS Write support under Debian (November 26, 2012):
As of Syslinux 6.03, a filesystem block size of 4KiB is supported.
As of Syslinux 6.03, an XFS partition in an "MBR" partition scheme is supported.
