%changelog
* Mon Aug 17 2026 Yann Collette <ycollette.nospam@free.fr> - 1.0-7
- install /etc/default/grub.d/50-kernel-audio-tuned.cfg to force a 4-second
  GRUB menu timeout (GRUB_TIMEOUT=4, GRUB_TIMEOUT_STYLE=menu) so the
  audio-tuned entry is selectable at boot; grub2-mkconfig is run in %%post
  (install/upgrade) and %%preun (full removal) to apply/restore the change

* Sat Jun 27 2026 Yann Collette <ycollette.nospam@free.fr> - 1.0-6
- 90-audio-tuned.install: skip non-standard kernel flavors (RT, LQX, Xanmod)
  by checking KERNEL_VERSION against KERNEL_AUDIO_TUNED_SKIP_FLAVORS before
  creating audio entries; defaults cover kernel-rt-mao (.rt), kernel-lqx-mao
  (lqx), and kernel-xan-mao (xan); set to "" in sysconfig to include all
- sysconfig: document and default KERNEL_AUDIO_TUNED_SKIP_FLAVORS

* Thu Jun 25 2026 Yann Collette <ycollette.nospam@free.fr> - 1.0-5
- 90-audio-tuned.install: fix sed delimiters (/ → |) so options containing
  slashes are handled correctly; move CPU detection into add) branch only;
  fix cleanup_entries to use printf instead of ls; wrap source sysconfig
  with || true so a syntax error cannot abort the hook
- spec: pre-delete *-audio.conf in %%post before regenerating so package
  upgrades with changed options actually update the boot entries; use
  %%{_prefix} and %%{_sysconfdir} macros in %%install and %%files
- sysconfig: add security note for nopti

* Sun May 10 2026 Yann Collette <ycollette.nospam@free.fr> - 1.0-4
- update to 1.0-4 - avoid some errors when there are no kernels to manage

* Tue May 05 2026 Yann Collette <ycollette.nospam@free.fr> - 1.0-3
- update to 1.0-3 - limit the number of audio tuned entries to installonly_limit

* Mon Mar 30 2026 Yann Collette <ycollette.nospam@free.fr> - 1.0-2
- update to 1.0-2 - add %post and %preun section

* Sun Mar 22 2026 Yann Collette <ycollette.nospam@free.fr> - 1.0-1
- initial version of the spec
