All daemons use a similar scheme to read their main config files and theirs drop-ins. The main config files are always stored in /etc/systemd directory and it's easy enough to construct the name of the drop-in directories based on the name of the main config file. Hence the new helper does that internally, which allows to reduce and simplify the args passed previously to config_parse_many_nulstr(). Besides the overall code simplification it results: 16 files changed, 87 insertions(+), 159 deletions(-) it allows to identify clearly the locations in the code where configuration files are parsed.
