`location` defines the preference of nodes for the given
resource. The location constraints consist of one or more rules
which specify a score to be awarded if the rule matches.
Usage:
...............
location <id> <rsc> {node_pref|rules}
node_pref :: <score>: <node>
rules ::
rule [id_spec] [$role=<role>] <score>: <expression>
[rule [id_spec] [$role=<role>] <score>: <expression> ...]
id_spec :: $id=<id> | $id-ref=<id>
score :: <number> | <attribute> | [-]inf
expression :: <simple_exp> [bool_op <simple_exp> ...]
bool_op :: or | and
simple_exp :: <attribute> [type:]<binary_op> <value>
| <unary_op> <attribute>
| date <date_expr>
type :: string | version | number
binary_op :: lt | gt | lte | gte | eq | ne
unary_op :: defined | not_defined
date_expr :: lt <end>
| gt <start>
| in_range start=<start> end=<end>
| in_range start=<start> <duration>
| date_spec <date_spec>
duration|date_spec ::
hours=<value>
| monthdays=<value>
| weekdays=<value>
| yearsdays=<value>
| months=<value>
| weeks=<value>
| years=<value>
| weekyears=<value>
| moon=<value>
...............
Examples:
...............
location conn_1 internal_www 100: node1
location conn_1 internal_www \
rule 50: #uname eq node1 \
rule pingd: defined pingd
location conn_2 dummy_float \
rule -inf: not_defined pingd or pingd lte 0
...............
Though this last example is wrong:
location conn_2 dummy_float \
rule -inf: not_defined pingd or pingd number:lte 0
