musl is mainly useful for tiny systems, a 40 MB partition is such a huge<br>
amount of space that the size of the C library no longer matters much.<br>
<br>
The size benefit of replacing glibc with musl is around 2 MB.<br>
<br>
A partition with an -Os build of Yocto with glibc+systemd (sic)<br>
is around 9 MB, together with bootloader and kernel this all<br>
fits in a 16 MB flash. Use compression for kernel and root<br>
filesystem and everything fits in a 8 MB flash.<br>
