nur den FreeBSD-Kernel bauen
- Wieso einen eigenen Kernel bauen? - Kernel-Module laden
ab FreeBSD 13
Einen angepassten Kernel bauen und installieren
Subversion ist bei FreeBSD Geschichte, die 13.0 wird das erste Release sein, welches nur noch per GIT abrufbar ist (und die älteren sind auch jetzt schon per GIT abrufbar). Dann müsste man das Paket "git" (oder "git-lite") installieren.
Den Quellkode bekommt man mit folgenden Befehlen:
> cd /usr/src > rm -fr * > git clone https://git.freebsd.org/src.git . > git checkout releng/13.0

nur einen bestimmten Kernel neu bauen
vor dem Kernel kompilieren muss die "Welt" kompiliert werden:
> cd /usr/src/ > make buildkernel KERNCONF=MYKERNEL > make installkernel KERNCONF=MYKERNEL > reboot
einmaliger Kerneltest
Wenn man nur (einmal) für den nächsten Reboot einen neuen Kernel testen möchtest.
# make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel # nextboot -k testkernel
einmaliger Test-Boot mit dem neuen Kernel
den neuen Kernel kann man mit einem ZFS-System leider nicht testen:
> make installkernel KERNCONF=MYKERNEL KODIR=/boot/testkernel > nextboot -k testkernel WARNING: loader(8) has only R/O support for ZFS nextboot.conf will NOT be reset in case of kernel boot failure > shutdown -r now
