This sort of functionality is useful when implementing some sort of recovery after being unable to start from the rootfs. Note that regardless of this concrete use case, systemd reboot command does support using arguments and there is no reason for not supporting this in klibc too. > - Doesn't Ubuntu always use busybox and glibc in the initramfs, anyway? > No, it uses klibc. > > (Alternately, try to convince upstream of the importance, as it doesn't > seem to have had any response yet.) > Upstream seems to be dead, there has been no response to any patch sent to the upstream list in years.
