Wouldn't this last one be :

NB:
Other uses of def->data.file.append could have used the

That is rather than "if (dev->data.file.append)", it could be "if
(dev->data.file.append != VIR_TRISTATE_SWITCH_ABSENT). It's just

expect some day in the future that append=on becomes the "default"?
You could have added an example where append='off' - it shouldn't
matter, but it is a legal option and the right XML should be generated
and the right .args would have append=off added to the command line.

It is guaranteed by the
check above, but ok, I will enhance this one as
well.
NB:
Other uses of def->data.file.append could have used the
virTristateSwitch constants (VIR_TRISTATE_SWITCH_ABSENT,
VIR_TRISTATE_SWITCH_ON, and VIR_TRISTATE_SWITCH_OFF).
That is rather than "if (dev->data.file.append)", it could be "if
(dev->data.file.append != VIR_TRISTATE_SWITCH_ABSENT). It's just
"safer" that way.
Good catch, thank you - fixed in v2.
Does adding ",append=off" make much sense?
Yes,
because it is explicit specification of desired behaviour.
It is always better than relying on defaults.
Or do you
expect some day in the future that append=on becomes the "default"?
I
believe 'on' is better than 'off'. But also believe that unlikely the
default value could be changed easily due to backward compatibility
considerations.
You could have added an example where append='off' - it shouldn't
matter, but it is a legal option and the right XML should be generated
and the right .args would have append=off added to the command line.
Yes, it is a
legal option - where should I add such an example?
I've send a patch for formatdomain.html.in with the attribute's
description,
but it is no accepted yet.
Thank you,
Dmitry.
