Well, devices look like this:
# ls -l /dev/*ps*
lrwxrwxrwx 1 root root 5 Apr 12 16:54 /dev/gps0 -> ttyS0
lrwxrwxrwx 1 root root 4 Apr 12 16:54 /dev/gpspps0 -> pps0
crw-rw---- 1 root ntp 253, 0 Apr 12 16:54 /dev/pps0
# ls -l /dev/ttyS0
crw-rw---- 1 root ntp 4, 64 Apr 12 16:54 /dev/ttyS0
# ls -l /chroot/ntpd/dev/
total 0
lrwxrwxrwx 1 root root 5 Mar 9 2018 gps0 -> ttyS0
lrwxrwxrwx 1 root root 4 Mar 9 2018 gpspps0 -> pps0
srw-rw-rw- 1 root root 0 Apr 12 16:39 log
crw-r--r-- 1 ntp ntp 1, 3 Mar 9 2018 null
crw-r--r-- 1 ntp ntp 253, 0 Nov 3 17:15 pps0
crw-r--r-- 1 ntp ntp 4, 64 Mar 9 2018 ttyS0
So a process running as ntp could access the necessary device files.
What else could be in the way of ntpd 'seeing' things?
