To update the root CA store in maemo-security-certman do the following:
1.Make sure you dont have maemosec-certman-common-ca package installed, if you do, remove it (and purge the config files)
2.Remove /etc/secure/s/certman.common-ca, /etc/secure/s/certman.blacklist, /etc/certs/common-ca and /etc/certs/blaclkist if they exist.
3.Build maemo-security-certman from this source tree and install all of 
the packages except maemosec-certman-common-ca
4.Run "make" in the updateca directory to compile parse-certdata-txt.
5.Download the latest certdata.txt file from http://hg.mozilla.org/mozilla-central/raw-file/tip/security/nss/lib/ckfw/builtins/certdata.txt via wget or similar and place it in the updateca directory.
6.Make a certs directory under the updateca directory
7.Run parse-certdata-txt
8.Run cmcli -l -c common-ca -a certs/*.pem
9.Run cmcli -l -c blacklist -a certs/*.untrusted
10.Remove etc/secure/s/certman.common-ca, etc/secure/s/certman.blacklist, etc/certs/common-ca and etc/certs/blacklist from the maemo-security-certman source tree
11.Copy /etc/secure/s/certman.common-ca, /etc/secure/s/certman.blacklist, /etc/certs/common-ca and /etc/certs/blacklist to the etc folder in the maemo-security-certman source tree
12.Update the changelog to reflect the updated certificates (its a good idea to include the revision of certdata.txt used at the time of updating the root CA store so people can see if its up to date or not)
13.Update the version number in configure.ac
