Initialize new git repo with a blank commit

It is useful to have a completely empty commit as the first commit. This is the command to do that:

GIT_AUTHOR_NAME='nil' \
GIT_AUTHOR_EMAIL='nil@example.com' \
GIT_COMMITTER_NAME='nil' \
GIT_COMMITTER_EMAIL='nil@example.com' \
GIT_AUTHOR_DATE='1970-01-01 00:00:01' \
GIT_COMMITTER_DATE='1970-01-01 00:00:01' \
git commit --no-gpg-sign --allow-empty -m 'NIL'

The hash for this commit should always be:

1bd23f7d074d57faf0913d7ce3ca84204bc67cee

source

I discovered that there is actually a built-in hidden commit that can be used for similar purposes.
