Hi, I think we should change these two variables in gem2deb/dh_ruby
DH_RUBY_GEM_INSTALL_WHITELIST_APPEND DH_RUBY_GEM_INSTALL_BLACKLIST_APPEND I think WHITELIST_APPEND can be changed to INCLUDE and BLACKLIST_APPEND to EXCLUDE. We can print a warning first and then remove them later. See https://m.timesofindia.com/gadgets-news/techies-you-may-no-longer-be-allowed-to-use-blacklist/whitelist-master/slave-while-coding/articleshow/76932892.cms for a background. -- Sent from my Android device with K-9 Mail.
