[rocky] need to install a CA cert in a initramfs

Dear Rocky community,

I am creating an initramfs and I need to install a CA cert in it. The reason is I need to download rootfs from an s3 bucket and the cert under the domain is self-signed.

I can copy the CA file through a module but I don't know how to reproduce the tasks done by the update-ca-trust command.

This is the module I am working on:

#!/bin/bash # module-setup.sh for cacert

# called by dracut check() { return 0 }

# called by dracut depends() { echo network return 0 }

# called by dracut install() { mkdir -p $initdir/etc/pki/ca-trust/source/anchors cp /root/certificate_authority.crt $initdir/etc/pki/ca-trust/source/anchors/ }

any advice on how to achieve this?

I am also open to other methods to get this working

thank yo uvery much
