Subject: Sys::Guestfs::Lib::open_guest: Remove freeform parameters.
X-Git-Tag: 1.0.84~4
X-Git-Url: http://git.annexia.org/?a=commitdiff_plain;h=33b4b759afe58c959bdc8b904d618aa1d699a240;p=libguestfs.git

Sys::Guestfs::Lib::open_guest: Remove freeform parameters.

Remove the ability to pass freeform parameters to Sys::Virt->new.
We don't use it, it makes the code more complex to modify, and
indeed there are no other args that Sys::Virt->new supports so
this would never be used.

Also change $readwrite to $rw to match parameter name.
