Very little is run prior to /usr being mounted in these setups. What is run isn't a daemon and very few of them print times. And if they were, they'd print it in UTC not local time. The only thing I can think of that might be user-visible would be boot -s to single user. Date will report UTC instead of local time in these setups (which these days have become somewhat rare).

Does this mean that installations with split / and /usr get broken?

Not in any real sense, no. Very little is run = prior to /usr being mounted in these setups. What is run isn't a daemon= and very few of them print times. And if they were, they'd print it in= UTC not local time.

The only thing I can think of= that might be user-visible would be boot -s to single user. Date will repo= rt UTC instead of local time in these setups (which these days have become = somewhat rare).
