I would rather see extN support included in the 'syslinux' command(s), 
but if this feature is added to the 'extlinux' command as proposed in 
this series of patches, then the resulting usage would need to be more 
accurate. For example, something *similar* to:

 Usage: [options] directory
 Usage for ext2/3/4 only: [options] <directory|device>

To be clear, the resulting output would need to be (at least) 2 
different rows, instead of a generic uniform usage output. In case 
different capabilities per supported filesystem are added in the 
future, then more details would need to be added to the usage output, 
accordingly.

Again, I would much rather see extN support added to the 'syslinux' 
command(s), instead of messing with the uniformity of the 'extlinux' 
installer.

TIA,
Ady.
