I generally don't like the idea of symlink change, but if it will go, I
will not argue. But, how existing installs will resolve that change
in one pass during install? Do I need static busybox to manually
replace symlink?
I even suggest making a hard link between them, so no symlink issue
will be there :)
It requires a bit more work without benefit. Point me please to
benefits page/mail, because I lost in my imap cache.
