It may be invoked via the installkernel mechanism or manually after building custom kernels.","What changed? =============","In version 111 of sys-kernel\/dracut the default for the hostonly_cmdline setting changed from enabled to disabled.","When enabled, this setting causes Dracut to attempt to detect which parameters are required on the kernel command line to boot the system. Examples are the root= parameter or parameters controlling partition decryption. These parameters are then included in the generated initramfs and appended to the kernel command line during boot.","Why has this setting been changed? ==================================","When enabled, Dracut's hostonly_cmdline setting may use the kernel command line of the running kernel (\/proc\/cmdline) to construct the kernel command line that will be embedded in the initramfs.","This can cause problems when Dracut is being executed from a live or rescue environment. In such cases an incorrect root= could be included in the embedded kernel command line which could lead to boot failure.","To prevent this behaviour from causing such unpleasant surprises, a check was added to sys-kernel\/installkernel to detect whether the kernel was being installed from chroot and if Dracut was configured to include an embedded kernel command line (hostonly_cmdline=yes).","While this check prevents boot failures, it also has the unfortunate side effect of creating a hard error that is triggered by default on new Gentoo installs. This has proven to be a significant stumbling block that new users often trip over. For this reason it was decided to disable the hostonly_cmdline setting in Gentoo's default settings for Dracut.","User Action Required (all users) ================================","With >=sys-kernel\/dracut-111, users need to perform a sanity check described in this news item.","This sanity check will ensure that kernel parameters required to boot successfully are still present in the kernel command line.

An example of when this is a user can end up compiling Firefox without audio support, meaning the user will have to add the USE flags and then compile Firefox a second time. This not only wastes time for the user, but also increases support workload by the volunteers that provides it.","This change will make PipeWire the default sound server for all Gentoo desktop profiles which support it, rather than just KDE Plasma profiles as was the previous norm[1].
