            Bug ID: 89656
           Summary: watchdog - external check
           Product: systemd
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: enhancement
          Priority: medium
         Component: general
          Assignee: systemd-bugs at lists.freedesktop.org
          Reporter: kl at vsen.dk
        QA Contact: systemd-bugs at lists.freedesktop.org

I currently have an issue on CentOS 7.. where nslcd simply stops working, and
systemctl/systemd restart just hangs.. I have to manually kill it.

until I "hopefully" find a fix.. I'd like to detect this situation and restart
the service.

Since systemd has this nice watchdog setup.. I'd like to use it, but
appearently it currently requires me to modify nss-pam-ldapd (ie. nslcd's
source).. 

I was hoping I could pursuade you to allow for a definition of an external
check.. (in my case something like: getent passwd | wc -l - and check count
larger than list in local passwd file)

So I don't have to write my own logic in a cronjob to fix it :)
