More specifically, I would like to permanently ( or at least in the short term) disable updating a particular package. I see that sudo apt-mark hold will do the job. But I am not sure will the "hold" remain persistent after a reboot. if it's not persistent I will have to run sudo apt-mark hold before every apt update.

apt use own database, plain files which can be seen in /var/lib/apt.
apt-mark use configuration file /var/lib/apt/extended_states
And answer to your question: changes which you made with apt-mark will be persistent.
