This is precisely one case where I see benefits: no need to correlate / and |

/usr. |

With the current way, this setup is broken if you don't pay attention: |
11 |
glibc is not backwards compatible (that is, stuff built for glibc 2.22 is |
12 |
not guaranteed to work with 2.21 and less), but you have glibc in /lib and |
13 |
stuff in /usr linking and dynamically loading it. If your nfs server |
14 |
updates glibc, you have to update every / on every of your workstations or |
15 |
fear the consequences of running binaries built for 2.22 but running |
16 |
against an older version. |
