clearly mount is using a symbol not provided by one of those shared libraries, but no clue which it is. However you dont need dash and mount and umount. Reason its working for genkernel is because its using busybox instead of normal system mount/umount/dash. Might want to try that. Smaller too.

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:

my init file in my initramfs:

#!/bin/dash

mount -t devtmpfs none /dev
mount -t proc none /proc
mount -t sysfs none /sys
echo 0 > /proc/sys/kernel/printk
cryptsetup luksOpen --allow-discards /dev/sda3 root

mount -o ro /dev/mapper/root /mnt/root
umount /dev /proc /sys
exec switch_root /mnt/root /sbin/init

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
