[pkg-ntp-maintainers] Bug#772790: ntp: cron job tries to delete .nfs files

[Paul Wise]

Package: ntp
Version: 1:4.2.6.p5+dfsg-2
Severity: important
X-Debbugs-CC: debian-admin at lists.debian.org

Usertags: needed-by-DSA-Team

DSA recently setup a couple of machines with a rootfs on NFS
(mips-aql-01/2). Both of them sometimes start getting errors like these
from the ntp cron job. Once the errors start, they do not stop until the
ntp service is restarted. Looking at the cron job I think the fix would
be to replace the find command with this one. It would be great if you
could get this included in the next Debian point release.

find "$statsdir" -name '*stats*' -type f -mtime +7 -exec rm {} \;

/etc/cron.daily/ntp:
rm: cannot remove `/var/log/ntpstats/.nfs00000000032a208e0005399d': Device or resource busy
