There doesn't seem to be too many disadvantages to using elf and
I assume pre-elf apps would still work.

Apart from changing Mint to recognise and load an ELF binary
does anything else have to be changed ?

Can you give me a quick summary of the advantages and disadvantages of all of the new options for ELF programs?

Dynamically linked ELF executable files:

*    are small
*    are more like executable files in other Unix-like systems
*    make it easier to upgrade libraries
*    run a bit slower than statically linked executable files


Statically linked ELF executable files that use shared libraries:

*    are tiny (smallest of the three options)
*    run very fast
*    are awkward to maintain when shared libraries change
*    are unique to BSD/OS and are not compatible with other systems


Statically linked ELF executable files that don't use shared libraries:

*    run fast (fastest of the three options, but not by much)

*    are compatible with other systems, but most ELF systems provide dynamically linked executable files
*    must be completely re-linked and replaced when you upgrade or change a library that they use
*    are enormous in size and memory usage (often several times the size of programs that use shared libraries)
