I do not have access to an Ubuntu system or chroot. I was hoping if someone could tell me if the Ubuntu wiki is accurate in saying:

For Quantal, merged /usr should be supported. On new systems installer should create {/bin, /lib, /sbin} symlinks into /usr.

Yes. As of at least Ubuntu 20.04, new installs use symlinks (existing systems won't be modified).

$ lsb_release -ds
Ubuntu 20.04 LTS
$ ll / | grep -E "usr|bin|lib"
lrwxrwxrwx   1 root root     7 Apr 23 15:02 bin -> usr/bin/
lrwxrwxrwx   1 root root     7 Apr 23 15:02 lib -> usr/lib/
lrwxrwxrwx   1 root root     8 Apr 23 15:02 sbin -> usr/sbin/
drwxr-xr-x  11 root root  4096 Apr 23 15:05 usr/

Seems like an unannounced change: Why are /bin and /sbin now symlinks in Ubuntu 20.04?

No.

$ ls -l /
total 2097260
drwxr-xr-x   2 root     root           4096 okt 28 11:46 bin

drwxr-xr-x  21 root     root           4096 okt 21 10:32 lib
drwxr-xr-x   2 root     root           4096 okt 18 20:32 lib64

drwxr-xr-x   2 root     root          12288 okt 28 11:46 sbin

You are looking at a proposal. Besides that: we follow Debian and unless they do not set this up we probably will not.

The link from Terrance is a little bit invalid: Fedora did this from release 17 (= 2012). See https://fedoraproject.org/wiki/Features/UsrMove on this. But Debian, Ubuntu never went for this setup.
