CA Cert question

[NO-ob]

Been playing around with a device on froyo. Just wanted to ask as i'm not sure if I modified my cacert file correctly

I couldn't get this tool to work so just made a couple scripts

The first deleted all certs in the cacert file from system/etc/security The second then added all of the certs from the debian package using keytool and bouncycastle

Is this correct or could I have messed something up by deleting all the certs already in the file? The reason I deleted them all was because majority of them were being flagged as already existing in the file
