The example that prompted this thread to begin with in the first place...
vars:
core_guppy::
"machines_list" slist =>
{
readstringlist("/var/cfengine/inputs/CoreGuppyMachines","#[^\n]*","[\n]",99999999,99999999)
};
db_guppy::
"machines_list" slist =>
{
readstringlist("/var/cfengine/inputs/DBGuppyMachines","#[^\n]*","[\n]",99999999,99999999)
};
app_guppy::
"machines_list" slist =>
{
readstringlist("/var/cfengine/inputs/AppGuppyMachines","#[^\n]*","[\n]",99999999,99999999)
};
classes:
"core_guppy" expression =>
strcmp("$(restricted_policy_hostlist_file)","CoreGuppyMachines");
"db_guppy" expression =>
strcmp("$(restricted_policy_hostlist_file)","DBGuppyMachines");
"app_guppy" expression =>
strcmp("$(restricted_policy_hostlist_file)","AppGuppyMachines");
So I define classes based upon a keyword, and then read in separate files into
a single slist variable array.
The workaround is to name each variable differently instead of trying to
overload the same variable. This also means that I populate the variable
regardless if I am going to use it or not.
