Subject: [9fans] exec permission on plan9
Date: Fri, 26 Feb 2010 17:28:37 +0000	[thread overview]
Message-ID: <7b956f03980157ec2a6357aaa14eb60f@quintile.net> (raw)

Who enforces the exec bit on plan9?

It appears to me (though my code may be buggy) that
the file server is expected to enforce the exec bit
in the file's modes when a file is opened with OEXEC.

I would have expected rc(1) to have checked the mode and
not to have tried to exec() the file if the exec bit in the
file's mode is not set.

Is it another case of "This is Plan9 not Unix" or perhaps
I am mis-remembering that too?

-Steve
