/sbin/installkernel is a script called by the kernels 'make install' as well as by the distribution kernels post install phase. sys-kernel/installkernel provides two paths for installing the kernel:

• the traditional installkernel, or
• systemd's kernel-install

In sys-kernel/installkernel versions lower then 20, systemd's kernel-install would default to the layout used for systemd-boot (layout=bls). To improve backwards compatibility with the traditional installkernel this is no longer the case in versions 20 and up. Instead the default layout setting when no other USE flags are enabled is a compatibility layout similar to the traditional installkernel (layout=compat).



User Action Required (systemd-boot users) ====================

Users of systemd-boot should:

• enable the "systemd-boot" USE flag

when upgrading to >=sys-kernel/installkernel-20.
