undercloud: Queens -> Rocky upgrade, xinetd locks tftp port

[Cédric Jeanneret]

Dear Stacker,

while doing a simple upgrade on my undercloud (queens -> rocky), I found out that the host tftpd run by xinetd prevents container ironic_pxe_tftp to start: port UDP:69 is still busy.

[stack@undercloud healthcheck]$ sudo netstat -laputen | grep :69
udp 0 0 192.168.24.1:69 0.0.0.0:* 0 21803 1246/xinetd

Stopping xinetd allows the container to start as expected, but apparently tftpd isn't the only thing that needs some xinetd, at least on non-containerized undercloud: rsync (for swift-storage) and mysql (via pacemaker) also has calls to xinetd resources.

We hence need an upgrade task at least for the ironic-pxe that drops the tftp listener from xinetd.

Cheers,

C.

    Remove tftp service and package upon upgrade to container

    In non-containerized over/undercloud, the tftpd service is
    supervised by xinetd.
    If we don't deactivate tftpd from xinetd, the UDP:69 port
    will still be in use, preventing the containerized tftpd
    service to start.
