Understand what you concern. but currently it has confused filesystem layout. currently /etc is located at read-only filesystem. since phone upgrade issue. it can update RO partition easily but RW is hard and difficult to maintain. anyway. a few files are symlinked to RW partition like /opt/etc /etc/localtime (symlink, RO) -> /opt/etc/locatime (symlink, RW) -> real local time fle. so there's no issue to use current glibc, double symlink handling, and system only change /opt/etc/localtime with proper local time zone. it's big change to use RW /etc and we can't confirm it's possible.
