Regarding a posting recently on fedora-devel, I'm considering what would be involved in making the self-signed certificates that various RPM's install as part of their %post/%pre section (openssl, sendmail, mod_ssl, proftpd, cyrus-imapd, etc) be a bit more meaningful than just:

# rpm -q --scripts cyrus-imapd preinstall scriptlet (using /bin/sh): ... if [ ! -f /etc/pki/cyrus-imapd/cyrus-imapd.pem ]; then pushd /etc/pki/tls/certs umask 077 /bin/cat<< EOF | make cyrus-imapd.pem -- SomeState SomeCity SomeOrganization SomeOrganizationalUnit localhost.localdomain root@localhost.localdomain EOF /bin/chown root.mail cyrus-imapd.pem /bin/chmod 640 cyrus-imapd.pem mv cyrus-imapd.pem /etc/pki/cyrus-imapd/cyrus-imapd.pem popd fi ...

and to that end, I wanted to have Anaconda/Kickstart allow one to populate a file such as /etc/certinfo with a few fields:

# # Certificate seed data, generated XX/XX/XXXX # C='US' ST='Idaho' L='Boise' O='Redfish Solutions, LLC' OU=''

as an example. Then the various scripts could use this as seed data.

The other thing that would be useful to have, but this is more of a packaging issue, would be to be able to re-run the %post/%pre scripts (or the idempotent sections of them) that generate certificates or otherwise network identity-derived configuration.

In cases where the CN (common name) of a certificate is generated from the hostname, for instance, and the hostname has changed (for instance the machine was rebooted in a production network with a DHCP configured to give it out a hostname).

An example of this is in the mod_ssl scripting:

# rpm -q --scripts mod_ssl postinstall scriptlet (using /bin/sh): umask 077

if [ ! -f /etc/pki/tls/private/localhost.key ] ; then /usr/bin/openssl genrsa -rand /proc/apm:/proc/cpuinfo:/proc/dma:/proc/filesystems:/proc/interrupts:/proc/ioports:/proc/pci:/proc/rtc:/proc/uptime 1024> /etc/pki/tls/private/localhost.key 2> /dev/null fi

FQDN=`hostname` if [ "x${FQDN}" = "x" ]; then FQDN=localhost.localdomain fi

if [ ! -f /etc/pki/tls/certs/localhost.crt ] ; then cat<< EOF | /usr/bin/openssl req -new -key /etc/pki/tls/private/localhost.key \ -x509 -days 365 -set_serial $RANDOM \ -out /etc/pki/tls/certs/localhost.crt 2>/dev/null -- SomeState SomeCity SomeOrganization SomeOrganizationalUnit ${FQDN} root@${FQDN} EOF fi

So, my question is basically this: what would be involved in modifying Anaconda and Kickstart to include (a) UI support for entering this information in a separate configure screen at install time, or (b) additional options for scripted installs?

It shouldn't be too much, right?

Thanks,
