Sorry if it's an unsuitable for questions ML, I've only found this one and the 
bugs-related.

We have a simple usecase of reading a partition table, and checking its 
properties, like `ped_partition_get_name()`.

The problem is: to get a partition table you need to call `ped_disk_new()` 
first. Which opens a disk in O_RDWR mode, resulting in dozens of excess events, 
including "remove/add" on older kernels, and just a lot of "change" ones with a 
newer kernel.

I tried setting `dev->read_only = 1` before calling a `ped_disk_new(dev)`, but 
the field seems ignored and the disk still gets opened with O_RDWR.

While using libparted with some other software at work, these events spam the 
system, causing UDEV to get overloaded with events which weren't supposed to 
happen in the first place. We were carrying some local patches to an older 
libparted that works around that by modifying an API, but I'd like to see if 
it's possible to get rid of that and just use the vanilla libparted.

So, any suggestions, how one can make `ped_disk_new()` open a device in 
read-only mode? Is that currently possible or does that require making changes 
to libparted?
