This works great. Wherever the SATA drive end up in the chain it gets
linked as /dev/sata1.

But, my brain is missing something else. I am doing LVM on these disks but
not "whole device" LVM, so, I also need symlinks for /dev/sdd1 etc to be
created as /dev/sata1_1, /dev/sata1_2, etc.

Never mind, I got it. But I'll post this for the archives anyway:

My SATA rules file (which runs AFTER the stock "persistent.rules" file) is
now two line for the single drive I have installed. Other lines will be
added for each drive I install later to link them to sata2 etc.

KERNEL="sd*[!0-9]",
ENV{ID_SERIAL}="SATA_WDC_WD2500YS-01_WD-WCANY1955037", SYMLINK+="sata1"

KERNEL="sd*[0-9]",
ENV{ID_SERIAL}="SATA_WDC_WD2500YS-01_WD-WCANY1955037",
SYMLINK+="sata1_%n"
