I would love to see a cron_d_job that places something in /etc/cron.d
instead. That has the advantage (on RHEL and Debian/Ubuntu, don't know
about the others) that no HUP to the daemon is necessary, any user can
be specified in any of the files, and the /etc/cron.d files can be
split up by purpose and not by user name.
Something like this, perhaps. Note how much simpler it is than cronjob().
bundle agent cron_d_job(basename, command, user, hours, mins)
# For adding lines to /etc/cron.d/basename crontabs for a user
# methods:
# "crond" usebundle => cron_d_job("markcrons", "/bin/ls","mark","*","5,10");
{
vars:
"crond" string => "/etc/cron.d";
files:
"$(crond)/$(basename)"
comment => "General batch jobs are added to $(crond)/$(basename)",
create => "true",
edit_line => append_if_no_line("$(mins) $(hours) * * * $(user)
$(commands)"),
perms => mo("644","root");
}
It may be good to also add cronjob_setenv and cron_d_job_setenv to set
the general environment: PATH, MAILTO, SHELL.
This has been a concern of mine ever since the cfperl days so it's good
to see a general way of doing it. I would agree with Seva, however,
that the other cron fields should be available if the user wants to
specify them. In a general library it makes sense to provide that even
if cfengine can do it externally. cfengine doesn't run frequently
enough in some setups.
Thanks
Ted
