[parted-devel] [PATCH 0/5] Add --readonly flag to parted

[Brian C. Lane]

Patches are also on GitHub - https://github.com/bcl/parted/pull/13

The benefit of this is that you can now easily read the device without
triggering any udev events with:

parted --script --readonly /dev/sda u s p free


After looking at the various options, I came up with a new one :)
Despite my aversion to adding new flags, I think this is the best way to
go about it. It doesn't depend on guessing the user's intent or
switching modes in the middle of operations.

It builds on the patch from Konstantin, and adds a --readonly flag that
opens it as read only, and leaves it as read only. This is slightly
different from previous behavior and use of read_only in that if
something else triggers read only mode it will not revert to write until
closed and exited. Which is fine, unexpected problems shouldn't really
keep trying write mode.

Let me know what you think.

Brian
