I think some programs can break, like those that assume / and /usr are both mounted early in the boot process.

I thought there was a discussion about some problems with systemd when / and /usr are different mount points (and only / is mounted early), but I can't find it at the moment.
Yes, I thought systemd requires /usr mounted by the initrd.
