# Notes on OpenSSL
# - Vendored (static link source build) ensures version consistency and easier
#   to build but increases size.
# - Non-vendored (dynamic link) uses system libraries, reducing size but may
#   cause compatibility issues.
# Choose based on security and footprint needs.
# For large deployments sharing OS images, OS updates can be easier for
# security patching than updating statically linked software.
