The best way is to use GPT labels, which are stored in the GPT header. They are portable, so keep working if the drive device name changes (ada0 to da1, say). GPT labels can be set with gpart modify. The labels appear in /dev/gpt/. As mentioned before, they might not appear if a partition is mounted due to GEOM "withering". GPT labels are enabled by default. If bsdinstall is disabling them, it is a regression. GPT IDs, on the other hand, are a unique generated ID code that can appear at the same time. Many of us find them not very useful and disable them in loader.conf. I have only upgraded systems to 10.1, so don't know what bsdinstall does on a new install.
