A lot of people are OK with the current approach. Really few
applications become unhappy if say,called "/bin/ls" instead of "ls".
So saying things are "broken" without switching to P flag is a bit
myopic view. In my experience, only some testsuites suffer failures.
The problem with updating the binfmt registration is that people may
have a mix of old and new qemu binaries. When we change the
registration, it means no old qemu anymore works. The "argc > 3" is
also a bit weak - it means that calling "ls -la ." would pass the test
even if "P" flag is not set, but qemu would pass wrong parameters to
the binary being run.
No doubt starting to use the P flag would be a improvement. But it
would be good to find a less breaky way manage the transition.
