Public bug reported:

I'm testing dracut in Ubuntu 25.10. My systems have a root filesystem
that's encrypted using LUKS. Decryption is done automatically on boot
via a Clevis/Tang pin (i.e., in the initramfs Clevis needs to access a
Tang server on the local network).

To make this work in Ubuntu 25.04 and initramfs-tools, I just had to
install clevis-initramfs. This caused the system to request an IP
address via DHCP and Clevis unlocking the root filesystem.

The equivalent to clevis-initramfs for dracut seems to be clevis-dracut.
After installing this, however, networking doesn't seem to be available
in the initramfs. The system does not even request an IP address from my
DHCP server.

* I tried running `dracut --regenerate-all --force` and also `dracut
--regenerate-all --force --hostonly-cmdline`. Neither version helped.

* I checked the output of `lsinitrd`:
  * In the section "dracut modules", this shows (beside others) clevis, clevis-pin-null, clevis-pin-sss, clevis-pin-tang, network, network-manager.
  * Under "dracut cmdline", this either shows nothing (after running `dracut --regenerate-all --force`) or the following block (after running `dracut --regenerate-all --force --hostonly-cmdline`):
