Bug #4679
Updated by Dominic Cleal about 10 years ago
If the installer is run on a host with upper case characters in its hostname, @puppet cert generate@ will create PEM files with lower case names. This will cause Apache startup errors. On re-runs, it also attempts to regenerate the certificate as the file it expects to be there isn't present (it has a lower case name).
