I want to run mysql_tzinfo_to_sql
whenever the tzinfo package (on Ubuntu Server) changes. I figured Puppet can take care of this.
I thought that either Puppet would react to a change in the package version, or if not, then to a change in timestamps of a file contained in the package.
The only way I can see to do this is to have a resource with no direct action, and have an exec depending on it.
The questions I have are:
- Is it possible to define a file that is only used to Notify another resource (such as exec)?
- Is it possible to define a package resource so that another resource (such as exec) is activated when the package changes or updates?
- Is it possible to define an exec resource that runs a shell command line (with pipes and redirection for instance) instead of a command from the filesystem?
Taken all together, it seems overwhelming.
FOLLOWUP: Fantastic answers! In the interest of completeness (and for the record), I should note the following:
- The complete shell command of interest is
mysql_tzinfo_to_sql | mysql -u root -p password
(it loads tzinfo into a MySQL database for MySQL use). - Auditing of
/etc/tzinfo
would be futile as this is merely the local time zone configuration; the goal is to watch for changes in the tzinfo data itself (thus the watching of/usr/share/zoneinfo
). - Likewise, the contents would be the wrong thing to watch - as they're likely not to change; the best would be to watch the mtime or all since the filetimes should change after every tzinfo update.
Also, James Turnbull wrote all about auditing when it was introduced. The Metaparameter Reference contains a short description of the workings of the audit
parameter.
