From the side of the enterprise people: /usr mountable ro. Please note that we have customers which are using exactly this feature.
Sure, they will just need an initramfs that can do that, if they want it to work in the future.
Actually, the long-term goal is to merge the useless split of / and /usr back to /usr and be able to mount /usr ro on every system. It's the same model as Android is doing with /system.
On servers I always have /, /usr, (/usr)/home, /var, and /tmp on separate filesystems in order to prevent accidentally filling up /. I know others are doing the same and I think that is a perfectly legitimate use case.
Sure, you only need to be able to mount /usr from initramfs. Init will not care where it came from. But it will no longer be supported to start init with an empty /usr.
Actually, /bin, /sbin, /lib, /lib64, ... should just be symliks to /usr, which will be mounted by initramfs, and likely be read-only by default in the future.
This is a bug of systemd and a violation of the FSH standard. For server systems a nogo.
Yeah, it's a violation of the rules of the stone age. Many of them just don't make sense anymore. We need to pick the nice parts of UNIX, and leave the silly things behind us to be able to survive. And the split of / and /usr very high on the list of things we like to get rid of.
Anyway, FHS documents current behavior, it can not be violated. If the current behavior changes, FHS needs to change, and people actually working on that.
Just double checked on that. There is no awareness at the FHS level that systemd implementation is pushing for the removal of /bin, /sbin, /lib, /lib64 and having everything pushed into /usr. Better speak up soon at fhs-discuss@lists.linux-foundation.org as the next release of FHS is in the works right now.
