can also chroot into the environment where you prepared the initramfs
image to test stuff, which will save you rebooting time.

Hi all,
After updating my musl, my custom initramfs had stopped working. Can
anyone give me a hand with this? I recompiled util-linux and updated
the related files in my initramfs and also tried building it with
static-libs but neither of these helped. On the other hand, the
initramfs I built using genkernel works just fine.
The init error:

/sbin/cryptsetup /bin/dash /sbin/switch_root /bin/umount
cd /usr/src/initramfs
