Through debugging (adding systemctl status output), I found that the service is failing with:

This can be fixed by installing ldconfig.real wherever ldconfig is needed.

This test passes using my PPA version of dracut: https://autopkgtest.ubuntu.com/results/autopkgtest-noble-enr0n-proposed-migration/noble/amd64/d/dracut/20240213_175455_6eeb7@/log.gz

[Launchpad Janitor (janitor)]

This bug was fixed in the package dracut - 060+5-1ubuntu2

---------------
dracut (060+5-1ubuntu2) noble; urgency=medium

  * d/p/ldconfig-real.patch: make sure ldconfig.real is installed where needed
