For me, I deploy a file called /etc/sudoers.d/local on every system that
I maintain which ensures that my own local user account, as well as
those of other admins, always have sudo access regardless of their group
Deploying that as part of a profile package that gets distributed via an
internal apt repository is far simpler than monkeying with sed.
It also works well for apt sources in /etc/apt/sources.list.d, dpkg
preferences in /etc/dpkg/dpkg.cfg.d, and syslog configurations in
/etc/rsyslog.d to name a few.
