Description of problem:
Logrotate file /etc/logrotate.d/atop provided by package atop-1.27-2.el6 depends on a pattern of atop logfiles to be /var/log/atop/atop_201[0-9][0-9][0-9][0-9][0-9], both in logrotate definition and in the postrotate action to remove old logs. That will stop working on year 2020.

Version-Release number of selected component (if applicable):
atop-1.27-2.el6

How reproducible:
Will be reproducible on 2020 always that /etc/logrotate.d/atop is left as is provided by package after installing.

Steps to Reproduce:
1. Install atop from epel6 (yum install atop)
2. Check contents of /etc/logrotate.d/atop provided by package atop-1.27-2.el6 (cat /etc/logrotate.d/atop )

Actual results:
/var/log/atop/atop_201[0-9][0-9][0-9][0-9][0-9] {
    missingok
    daily
    nodateext
    rotate 1
    ifempty
    nocreate
    postrotate
      /usr/bin/find /var/log/atop/ -maxdepth 1 -mount -name atop_201\[0-9\]\[0-9\]\[0-9\]\[0-9\]\[0-9\]\* -mtime +40 -exec /bin/rm {} \;
    endscript
}


Expected results:
/var/log/atop/atop_[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9] {
    missingok
    daily
    nodateext
    rotate 1
    ifempty
    nocreate
    postrotate
      /usr/bin/find /var/log/atop/ -maxdepth 1 -mount -name atop_\[0-9\]\[0-9\]\[0-9\]\[0-9\]\[0-9\]\[0-9\]\[0-9\]\[0-9\]\* -mtime +40 -exec /bin/rm {} \;
    endscript
}
