Using apt-get update chowns user to mongodb

Running apt-get update on the servers used by Ops Manager can have the sad consequence of changing the owner to the mongodb user from mongodb-mms user, potentially breaking backups for customers. The bit of code for the package that seems to apply here:

Post-install:

# create a mongodb group and user

if ! getent passwd mongodb >/dev/null 2>&1; then

adduser --system --no-create-home mongodb

addgroup --system mongodb

adduser mongodb mongodb

fi

# create db -- note: this should agree with dbpath in mongod.conf

mkdir -p /var/lib/mongodb

chown -R mongodb:mongodb /var/lib/mongodb

# create logdir -- note: this should agree with logpath in mongod.conf

mkdir -p /var/log/mongodb

chown -R mongodb:mongodb /var/log/mongodb

However, mongod is running as the mongodb-mms user (because Ops Manager's default user is mongodb-mms). Suggestion: chown if the directories don't previously exist, else no chown.
