understand, no check, just to try to run ezstream, while mount point is
not in use, am i right?

<on-disconnect> should be the best way, but it seems not working in
version 2.4.4-1 which we are using

this seems is latest version in ubuntu 18.04

$ apt-cache policy icecast2
icecast2:
  Installed: 2.4.4-1
  Candidate: 2.4.4-1
  Version table:
 *** 2.4.4-1 500
        500 
http://download.opensuse.org/repositories/multimedia:/xiph/xUbuntu_18.04
./ Packages
        100 /var/lib/dpkg/status


or is there 2.5.x package, for ubuntu 18.04?
