PSARC/2004/480 has not been done for fun but because Solaris urgently
_needs_ the code from star for compatibility.
Your claim is wrong in two ways:
- GNU tar does _not_ come with a copy of the original BSD rmt.
It comes with some important extensions that give better
compatibility. Well, it is based on the original 1981 rmt source
from BSD... but this does not mean anything.
- Solaris /etc/rmt is not even truely _based_ on the original
BSD rmt. It has been written at UCB for Sun but it behaves
different. Sun rmt implements some other addidions that
give better compatibility and it implements it's code
dual-threaded which makes it ~ 30% slower than the star
implementation.
Star's "rmt" implements all additions from all known rmt implementations
and it implements own additions that give further enhanced compatibolity.
Star's rmt in addition implements:
- IPv6 support
- ssh support
- better and configurable security.
Star's "rmt" server is the only rmt server that nicely plays with all rmt
clients.
It makes no sense to add just another rmt implementation that inly gives very
limited compatibility.
