Subject: SectionConfig: always write out explicitly set booleans
X-Git-Url: https://git.proxmox.com/?p=pve-common.git;a=commitdiff_plain;h=d152f8b0ee639fc08138a19fef8653346ed4762b

SectionConfig: always write out explicitly set booleans

Because when only writing the ones which are true we're
breaking the ones which default to true (like the mkdir
option on directory storages, where we need a false value
to be written out explicitly).
