We add a regular LookupBoolean that can fail lookups, which is used by the WithDefault version. We want to use this directly later in some places. It is fina to change API here because this has not been in a release yet. Signed-off-by: Alexander Larsson <alexl@redhat.com>
The ReadOnly and the RunInit keys affect options that have a variable default (configurable in containers.conf). This means we need to handle them a bit differently in quadlet to allow overriding the default. For example, we can't assume ReadOnly=false doesn't need to add any argument because no argument may mean readonly=true if the default is changed. We now don't add any argument (leaving the default) if the key is not specified, or we always add an argument (--foo or --foo=false) if the key is specified (overriding whatever the default is).

There was a problem hiding this comment.
Since 'LookupBooleanreturnfalsewhen the key is not found. Is there any advantage of usingLookupBooleanWithDefaultwithfalse` as default?
There was a problem hiding this comment.
Not technically, but it imho makes the code intention clearer.

Some CI network hickup it seems. |
