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:

how I update my initramfs:
lddtree.py --copy-to-tree /usr/src/initramfs /bin/mount /sbin/cryptsetup
/bin/dash /sbin/switch_root /bin/umount
cd /usr/src/initramfs
find . -print0 | cpio --null --create --verbose --format=newc >
/boot/custom-initramfs.img
