# a pristine copy of every config under /usr/share/twiy/defaults/nginx. We

# place configs from that stash here and NEVER overwrite a file that already
|
|
# exists — our copy is dropped beside it as <file>.new instead (e.g.
|
|
# nginx.conf.new). An upgrade therefore never changes an admin-edited config.

# /hostdata is left entirely to the admin: we only make sure the dir exists,
