   Package: initramfs-tools   
   Version: 0.148.3   
      
   * summary   
      
   update-initramfs no longer includes /lib/modules//updates   
   directory, this means out of tree drivers are not loaded during boot.   
   I could not find reference to this behaviour change in release notes   
      
   * update-initramfs in debian 12 (initramfs-tools 0.142) includes the   
   updates directory when building initrd.img, example:   
      
   root@testhost:~# update-initramfs -u -v 2>&1 > /root/update.1   
      
   root@testhost:~# grep sfc /root/update.1   
   Adding module /lib/modules/6.12.51-u1-amd64/kernel/drivers/net/e   
   hernet/sfc/falcon/sfc-falcon.ko.xz   
   Adding module /lib/modules/6.12.51-u1-amd64/updates/dkms/sfc.ko.xz   
      
   root@testhost:~# lsinitramfs /boot/initrd.img-6.12.51-u1-amd64 | grep sfc   
   usr/lib/modules/6.12.51-u1-amd64/kernel/drivers/net/ethernet/sfc   
   usr/lib/modules/6.12.51-u1-amd64/kernel/drivers/net/ethernet/sfc/falcon   
   usr/lib/modules/6.12.51-u1-amd64/kernel/drivers/net/ethernet/sfc   
   falcon/sfc-falcon.ko   
   usr/lib/modules/6.12.51-u1-amd64/updates/dkms/sfc.ko   
      
      
   Reference : https://man7.org/linux/man-pages/man5/depmod.d.5.html   
   Behaviour aligns to:  By default, depmod will give a higher priority   
   to a directory with the name updates   
      
      
   * update-initramfs in debian 13 (initramfs-tools 0.148.3) does not   
   include the updates directory, this means the dkms modules are not   
   loaded correctly at boot.   
      
   # modules are present   
   root@testhost:~# find /lib/modules/6.12.51-u1-amd64/ -type f | grep sfc   
   /lib/modules/6.12.51-u1-amd64/kernel/drivers/net/ethernet/sfc/fa

   root@testhost:~# update-initramfs -uv 2>&1 > /root/update.1   
   root@testhost:~# grep sfc /root/update.1   
      
      
   # eventual initrd.img does not include the modules   
   root@testhost:~# lsinitramfs /boot/initrd.img-6.12.51-u1-amd64 | grep sfc   
   usr/lib/modules/6.12.51-u1-amd64/kernel/drivers/net/ethernet/sfc

   * other   
   A very similar issue was reported here on ubutnu 24.02 ( I believe deb13 based)   
   https://discourse.ubuntu.com/t/update-initramfs-ignores-dkms-module/63923   
      
      
   * workaround   
   My current workaround is to install dracut fully.
