Previously callbacks would return a list of flags, such as []
or [`Created_files].
In this commit we introduce two new objects, filesystem_side_effects
and device_side_effects (the latter is not used yet).
The callbacks that create files now need to call
side_effects#created_file ()
instead of returning flags.
There is no functional change in this patch.
It now appears in the respective man pages as:
--root-password selector
or:
--password selector
This avoids confusion from people who think these command line options
take the password directly.
- Use 'op' instead of 'xxx_op' for operation table.
- Add a 'defaults' for the operation table and remove any default
values.
This is just code motion and there is no functional change.
Operations that need to work directly on guest block devices will fail
because the block devices are busy. Therefore add a phase with the
filesystems unmounted, and allow operations to specify that they need
to work in this phase.
Note that this support is optional: To enable it, install the
ocaml-gettext library from
http://forge.ocamlcore.org/projects/ocaml-gettext . If this library
is not installed, then configure detects this and inserts dummy
gettext functions that do nothing.
All current operations are enabled by default.
Also:
* The POD description is split into a heading and the description body.
* An 'enabled_by_default' flag is added to the structure.
