Hi! I used cfengine successfully a decade ago. Now I'm trying to use it
again.
I'm trying to get started with cfengine3 using the example config files. I
noticed a few elements from cfengine_stdlib.cf are redefined in site.cf,
update.cf, and library.cf. I was surprised that the example configuration
files don't work with the standard library.
The stdlib's body action immediate { ifelapsed => "0"; } but update.cf's
version has { ifelapsed => "1"; }. Is there any harm in using "0" instead of
"1"? Should one of them be renamed to almost_immediate?
In the documentation, process_select is sometimes documented as
select_process. Are both valid?
In the documentation, "left hand side" is misspelled "left hand size".
When using process_select, is it possible to pass the regex process selector
(the leftmost string) to the process_select body? I wanted to match named
processes only if they were owned by a particular owner. I wound up with:
processes:
".*" process_select => process_owner("foobar .*", "root");
...
body process_select process_owner(command, owner) {
command => "$(command)";
process_owner => { "$(owner)" };
process_result => "!(command.process_owner)";
}
but I wanted something like:
processes:
"foobar .*" process_select => process_owner("$(lhs)", "root");
How do I use readtcp with an empty "data to send" string, to set a class if
a port is (not) accepting connections? I wound up sending something and
checking the string against regcmp(".+", "$(data_read)");
How do I read a pid from a pid file for use in processes: ?
Thanks,
Daniel Holth
