If a system may or may not have a specific file and you only want to
evaluate the promise if the file exists, this is an example of the only
way I can see to do that:
classes:
"file_exists" expression => fileexists("/var/adm/kern.info");
files:
file_exists::
"/var/adm/kern.info"
rename => rotate("5");
I was thinking that it might be nice to have something like an
"optional" attribute that would ignore the promise if the file doesn't
exist (maybe defaulting to "false"), simplifying such promises:
files:
"/var/adm/kern.info"
optional => "true",
rename => rotate("5");
Has anyone else thought about this or know of something that I might be
missing? I'm setting up some log rotation (hence this particular
example) and currently we have a number of such "optional" log files on
many systems (but we're working on cleaning that up).
Thanks,
Justin
