When I installed ntp (Running Gentoo - Installed ntp as a "package")&
first ran it, it complained about the content of ntp.drift so i seeded
it with 0.00 and restarted the daemon. It didn't complain on the restart
so I assume it can read the file.
drwxr-xr-x 2 ntp ntp 4096 Jan 28 08:28 .
drwxr-xr-x 13 root root 4096 Jan 25 15:24 ..
-rw-r--r-- 1 ntp ntp 6 Jan 28 08:28 ntp.drift
I can't answer the chroot question.
Thanks.
