11 They tested it? Are you referring to the platforms from bug #417451?
12 (excluding the Prefix platforms, because in the Prefix tree
13 gen_usr_ldscript just works, because it breaks existing installs to

26 I thought so too, until I got dangling symlinks for older zlib for some
27 reason (preserve-libs? ebuild?) which wasn't really a funny experience.
28 So, before this is done, we must test it in all forms, not rely on theory.

30 Alexis' profile suggestion nicely allows existing installs to remain as
31 is, new installs to be without /usr-split, and people to move over when
32 they deem that a good idea.
