Hello,
This is not a bug, it's a feature; install creates a file and either
sets permissions to 0755, or if -m is specified sets the permissions
to whatever was requested *relative to 0000*. All but the last point
are explicitly mentioned in the man page, which reads:
-m Specify an alternate mode. The default mode is set to rwxr-xr-x
(0755). The specified mode may be either an octal or symbolic
value; see chmod(1) for a description of possible mode values.
Here's the relevant bit from chmod(1):
+X make a directory or file searchable/executable by everyone
if it is already searchable/executable by anyone.
It seems clear to me at least that since we're not modifying, but
rather specifying permissions, there are no existing permissions
to leave untouched, hence "+X" has no meaning whatsoever.
Setting the permissions relative to those of the original file seems
to me like a particularly bad idea, so there's nothing to fix.
This PR can be closed
