Patch for fix this bug

This is an old bug that was fixed some time ago at the Arch Linux forum, but not in the upstream: https://bbs.archlinux.org/viewtopic.php?id=237592 .

Unit of systemd cann't get the answer from xdm and timeout ends. Fast solution without package modification is infinite timeout for unit of systemd, but it's breaks the boot chain (from the systemd point of view boot chain never ends).

Thanks, Artem.

I'm haven't had enough coffee to understand where the configure.ac file is that needs to be patched.

[marja@localhost ~]$ urpmf configure.ac | grep xdm
[marja@localhost ~]$

Did you notice that infinite loop in Mageia, too?

$ tar tvf xdm-1.1.12.tar.bz2 | grep configure.ac
-rw-r--r-- alanc/staff   20231 2019-03-03 01:06 xdm-1.1.12/configure.ac
$ rpm -qpl xdm-1.1.12-1.mga7.src.rpm | grep .tar.bz2
xdm-1.1.12.tar.bz2

File configure.ac in the tarball xdm-1.1.12.tar.bz2, the tarball xdm-1.1.12.tar.bz2 in the xdm-1.1.12-1.mga7.src.rpm package. Patch just needs to be added to the sources. After that package must be rebuilt. I have done this steps and bug was gone.

$ rpm -q xdm
xdm-1.1.12-2.mga7
