Title:
  dracut generated initramfs doesn't contain necessary files for iscsi
  boot

Status in dracut package in Ubuntu:
  In Progress

Bug description:
  When running Ubuntu 24.10 (Oracular Oriole) and switching from
  initramfs to dracut (by installing dracut packages and following
  instructions in /usr/share/doc/dracut-core/README.Debian), the
  initramfs generated by dracut won't include the necessary files to
  allow an instance to boot from iscsi. The following packages were
  installed:

  ii  dracut                                 103-1ubuntu2                             all          Initramfs generator using udev
  ii  dracut-core                            103-1ubuntu2                             amd64        dracut is an event driven initramfs infrastructure (core tools)
  ii  dracut-install                         103-1ubuntu2                             amd64        dracut is an event driven initramfs infrastructure (dracut-install)
  ii  dracut-network                         103-1ubuntu2                             all          dracut is an event driven initramfs infrastructure (network modules)

  
  When trying to boot from iscsi by adding the following cmdline to grub (booting from ISCSI in an Oracle Cloud instance):

  BOOT_IMAGE=/vmlinuz-6.8.0-1005-oracle
  root=UUID=f692dbf6-c1a4-4a31-8585-2571fbbd2f7e ro console=tty1
  console=ttyS0 nvme.shutdown_timeout=10 libiscsi.debug_libiscsi_eh=1
  crash_kexec_post_notifiers rd.luks=0 rd.md=0 rd.dm=0
  rd.net.timeout.carrier=5
  rd.iscsi.param=node.session.timeo.replacement_timeout=6000
  net.ifnames=1 ipmi_si.tryacpi=0 ipmi_si.trydmi=0
  libiscsi.debug_libiscsi_eh=1 loglevel=4 rd.net.timeout.dhcp=10 ip=dhcp
  netroot=iscsi:169.254.0.2:::1:iqn.2015-02.oracle.boot:uefi

  The boot fails with:

  [  OK  ] Reached target network-online.target - Network is Online.
           Starting iscsid.service - iSCSI initiator daemon (iscsid)...
  [FAILED] Failed to start iscsid.service - iSCSI initiator daemon (iscsid).

  [    7.913629] dracut-initqueue[521]: Warning: Target discovery to 169.254.0.2:3260 failed

  Eventually the instance will drop to an emergency shell and we can
  check the error in details:

  # journalctl -u iscsid --no-pager

  Sep 18 19:58:40 localhost (hecks.sh)[584]: iscsid.service: Unable to locate executable '/usr/lib/open-iscsi/startup-checks.sh': No such file or directory

  Sep 18 19:58:40 localhost systemd[1]: Failed to start iscsid.service - iSCSI initiator daemon (iscsid).

  Extracting the initramfs generated by dracut, we can see that
  /usr/lib/open-iscsi/startup-checks.sh is not included:
