This is totally fair. QEMU has zero documentation on the intended limits on
these two options but the QEMU source masks them with 0777. Given that we
only have the implementation to go off of rather than the intent, should we
assume that sticky bits will never be supported or that it's an
shortcoming in the QEMU code?
I can either do similar masking or mask with 07777 and send along the
to QEMU as a 5-digit number (the first digit being a leading 0) .The
could then say the behavior is ultimately determined by QEMU but, currently,
sticky bits are not supported?
