That's very cool.

Following your recent message about how you use this to set variables, `
I tried to use it and ran into some problems. For example, I tried:
ReplaceAll "^enableRollbacks=.*$" With "enableRollbacks=1"
This produced the following output:
Begin editing /etc/sysconfig/rhn/up2date
Checking for global replace/^enableRollbacks=.*$/enableRollbacks=1
cfengine: WARNING: Non-convergent edit operation ReplaceAll
[enableRollbacks=1] With [^enableRollbacks=.*$]
cfengine: Line begins [enableRollbacks=0]
cfengine: Replacement matches search string and will thus replace every
time - edit was not done
cfengine: Error editing file /etc/sysconfig/rhn/up2date
However, that edit is convergent. It will match every time, but the
result will always be the same. I assume the warning above is supposed
to guard against edits like:
ReplaceALL "ab" With "abab"
which should be prevented. I think cfagent should test whether the
replacement will be *different* every time.
Best,
Brendan
