I see two flaws in the glibc: first it is bloated, second the 
static version does not contain all functions. To my knowledge, the 
second flaw is by the personal will of Ulrich Drepper.

     These are two reasons to prefer Musl libc. Nevertheless, Glibc 
designs the standard and this is not without merit. And I am not 
advocating to convert Devuan to Musl :-) there are more important things 
to do.

     Thanks Jude!
