Yes, it is installed. This is from the instance that I used to create
the image that later on boots from iscsi:
ubuntu at oracular-dracut:~$ sudo dpkg -l dracut-network
Desired=Unknown/Install/Remove/Purge/Hold

+++-==============-============-============-====================================================================
ii dracut-network 103-1ubuntu2 all dracut is an event driven initramfs infrastructure (network modules)
I noticed that, when regenerating the initramfs, we get an error that says:
dracut[I]: *** Including module: iscsi ***
Failed to enable unit: Unit iscsiuio.socket does not exist
Not sure if its related. Full output:

Title:
dracut generated initramfs doesn't contain necessary files for iscsi
boot
Status in dracut package in Ubuntu:
New
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

netroot=iscsi:169.254.0.2:::1:iqn.2015-02.oracle.boot:uefi
The boot fails with:

Eventually the instance will drop to an emergency shell and we can
check the error in details:
# journalctl -u iscsid --no-pager

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