Yo All!
Sorry, a typo:

I start this way, with a capital S:
# ptp4l -S -f /etc/ptp-howto.conf
strace shows me a bit of SHM action:
# strace -o tmp ptp4l -S -f /etc/ptp-howto.conf
shmget(0x4e545032, 96, IPC_CREAT|0600)
Yo All!
About a year ago I was running tests feeding time from ptp4l to
ntpd using a SHM. I just repeated the experiment after updating
my linuxptp to git head, and now no luck.
My version:
# ptp4l -v
1.8-00063-g5ce04f9
I'm pretty much following the instructions here:
