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:

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