   A smaller one (speaking of linuxes: uclibc vs musl vs glibc) doesn't mean "more secured" automatically.  Mostly it means one needs to implement that extra functionality (provided with bigger libs) in user software.  If there's no need in that, a smaller is better, otherwise it's the opposite case.
