# 1) We can't upgrade from uclibc to uclibc-ng via a soft blocker since portage
|
|
# will delete the ld.so sym link prematurely and break the system. So we
|
|
# will hard block and give manual migration instructions.
|
|
# 2) Currently uclibc and uclibc-ng's iconv are in bad shape. We've been using
|
|
# the breakout library. The disadvantage here is that we have to sprinkle
|
|
# LDFAGS=-liconv on build systems that need to link against libiconv.
