Well, you're literally right, but I wonder if you've
gandered Policy v220.127.116.11, Sec 3.3.4:
Restrict your script to POSIX features when possible so that it may use
/bin/sh as its interpreter. If your script works with ash, it's probably
POSIX compliant, but if you are in doubt, use /bin/bash.
I was simply pointing out that this recommendation in policy is not to be
taken too literally, and in fact 'ash' isn't very POSIXly correct after
all. Some developers---not you, clearly---might say "well, 'command -v'
doesn't work in ash, it must be non-POSIX.
[Please, next time, Mark, don't assume I'm a total idiot.]
