Returning to the topic: Is it possible to modify a global slist? I could use this if I want to keep a list of all cronjobs that should be present in root's crontab in memory and at the end of cfengine's execution I write them to disk. Why? Because by working with single "edit_line" statements in different bundles it is not possible to guarantee that the crontab (or any other file) is exactly as I'd like it to be. There may be extra junk, there may be misspelled commands, etc. However if I start from scratch with an empty file and just add single lines scattered through different bundles, then this will never converge. If I collect all the lines that I want in memory and write them out in a single run, then I can make use of cfengines intelligent editing - the "intended" state is assembled in memory and only if "intended" and "current" differ then an actual edit happens and the file is being replaced. This does not only apply to cron, where the issue could be evaded by using /etc/cron.d/ etc. It also applies to /etc/passwd, /etc/motd, /etc/fstab, /etc/hosts.(allow|deny), /etc/security/limits.conf or any other file that might be interesting to different users and/or applications. _______________________________________________ Help-cfengine mailing list Help-cfengine@cfengine.org https://cfengine.org/mailman/listinfo/help-cfengine
