[ptxdist] ptxdist: BUSYBOX_NTPD blocks NTP

Hello all,

I am using the ntpd applet in busybox but also wanted to enable the ntpdate
program (yes I know use of ntpdate is not recommended in general but this
is for a very specific use case). However I see that ntpdate is part of the
"ntp" package and that the ntp package is blocked by BUSYBOX_NTPD. From
rules/ntp.in:

menuconfig NTP
        tristate
        prompt "ntp                           "
        select OPENSSL          if NTP_CRYPTO
        select ROOTFS_VAR_CACHE if NTP_NTPD
        select LIBC_M
        select LIBC_RT
        select GCCLIBS_GCC_S
        select LIBMD
        depends on !BUSYBOX_NTPD || ALLYES

[...]
config NTP_NTPDATE
        bool
        prompt "install ntpdate"
        depends on NTP


Obviously one would not want to run two ntp services at the same time, but
since busybox lacks an ntpdate command, there are cases where one would
want to use ntpdate from the NTP package while still using Busybox's ntpd
for everything else.

My question is: Is there any reason why this wouldn't work? Was the
"depends on !BUSYBOX_NTPD" line added just to avoid the possibility of the
two ntp services running at the same time? Or is it there to guard from
other possible problems/issues?

Thank you,
