dracut-install crashing

[davidlohr]

While this is not a bug in this project, 'run_qemu.sh' has a way of always triggering dracut-install(1) segfaults during the install_build_initrd phase. I can reproduce this on every run in Fedora 36 and Tumbleweed, it can happen multiple times as well during the same phase.

@davidlohr Interesting - I haven't seen that before, I'm on Fedora 36 too, with

$ dracut --version
dracut 056-1.fc36

[davidlohr]

Yup, same version of dracut as well.

fwiw here's the bt (albeit no debug symbols)
