Hi List
I'm using the "unit_copy_edit.cf" example from the units/ directory to
perform convergent copying and editing of configuration files to a cf-agent
host.
My unit_copy_edit copies template config files, creates staging files and
then should generate final configurations, but instead it dies with the
following types of error message for 2 files I'm trying to copy and edit
(when doing cf-agent -f promises.cf):
---
File /var/cfengine/staging/etc/pf.conf was marked for editing but could not
be opened
File /var/cfengine/staging/etc/rc.conf was marked for editing but could not
be opened
---
I note that the staging files are created:
---
[r...@server1.ops.exyzed.co.na /var/cfengine/staging/etc]# ls -l
total 4
-rw-r--r-- 1 cfengine 1010 1872 May 10 11:15 pf.conf-staging-file
-rw-r--r-- 1 cfengine 1010 1239 May 10 11:15 rc.conf-staging-file
---
Here is an example of the configuration blocks from the file I'm using
(based on unit_copy_edit.cf):
