Actually, although I still shink that pacemaker should not allow
modification of that options, source of my problem is that crmsh doesn't
initialize <cluster_property_set/> node with original values when it is
doing load update.

Example (very long lines are stripped for readability):

property $id="cib-bootstrap-options" \
# crm -d configure load update u.crm

I would expect that only one option is modified, but crmsh intend to
remove all others.

May be it is possible to fix it by one-line crmsh patch?

Kristoffer, Dejan?
