There's a difference whether you logged in as root or su-ed to root. In
the latter case /home is still in use by the user you su-ed from.

Even though it is not strictly necessary to init 1 you must make sure
not a single user that uses /home for their home directory is logged in
and no system user accesses files there (f.e. apache configured with
home dirs) when attempting to move /home.

Regards,
Leonard.

Doing a lsof showed no open files against /home. Something else is
locking it, not a user process. Also disabled SELinux, did a init 1,
and only way to remove it was via single user by passing
init=/sysinit/bin/sh

It sounds like /home is being managed by something in the kernel, then.

Are you exporting /home via NFS or SMB?  AutoFS?  I'm trying to think
what would start at runlevel 1, although if this is c7 that might not
be a valid description anymore, perhaps services are being started at
'rescue.target'.
