Yes. A unit with Requires=sysroot.mount, After=sysroot.mount will be started only after /sysroot has been mounted. But it looks like the resize script should run *before* the automatic mounting. If the script is made into a Type=oneshot unit, adding Before=sysroot.mount will delay mounting until the unit has finished. I'm not sure though, what's the best way to make sure that it is run after the root device has been detected, unless the root device name is known in advance. If it is, Requires=<device>.device, After=<device>.device should be added.
