You need to use canonify, and then use the variable in a class expression.
Canonify ensures that the string only has characters that are valid in class
names. Using your example:
bunde agent my_app {
vars:
"server_type" string => (read from file and it can be: db_server,
app_server, dns_server, etc.);
"c_server_type" string => canonify("${server_type}");
classes:
"${c_server_type}" expression => "any";
files:
db_server::
"XXXXXXX"
app_server::
"XXXXXXX"
dns_server::
"XXXXXXX"
etc..
}
