Package: atop
Version: 2.2.6-4
Severity: normal

Hi,

..my first attempt wound up in the partially wrong place, upstream:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=913364 because of
https://bugs.devuan.org//cgi/bugreport.cgi?bug=256

Package: atop
Version: 2.2.6-4
Severity: normal

--- Please enter the report below this line. ---

..on installing atop, I found things going at a glacial pace, a 
wee part of global climate change, and this fine new cron job:
root@box:~# cat /etc/cron.d/atop
PATH=/bin:/usr/bin:/sbin:/usr/sbin

# daily restart of atop at midnight
0 0 * * * root if [ -d "/run/systemd/system" ]; then systemctl restart
atop; else /usr/share/atop/atop.daily \& ; fi

..commenting it out, "brought back life."

..we need to keep an eye out for such systemd tricks causing such DOS,
one way is chk which init system is installed, and then install the
correct cron job file.
root@box:~# dpkg -l atop |grep atop |fmt -tu
ii atop 2.2.6-4 amd64 Monitor for system resources and process activity
