[pkg-ntp-maintainers] Bug#893542: ntpsec-ntpviz: shares /var/log/ntpstats with ntp, which gets zapped when ntp is purged

[Julian Gilbey]

Package: ntpsec-ntpviz
Version: 1.0.0+dfsg1-5
Severity: serious

I installed the ntpsec suite, then purged the ntp packages.
Unfortunately, this zapped the /var/log/ntpstats directory, which is
needed by ntpsec-ntpviz.  There needs to either been some agreement
between ntp and ntpsec about the use of this directory, or ntpsec
needs to use a different log directory.

Best wishes,
