From: Felix Fietkau Date: Fri, 29 Sep 2017 10:30:52 +0000 (+0200) Subject: util-linux: avoid using the getrandom syscall X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=e64463ebde554071431514925825e2c30f2b6998;p=librecmc%2Flibrecmc.git util-linux: avoid using the getrandom syscall getrandom blocks until the random pool is being initialized. Unfortunately, this code is being called early during init to create the overlay filesystem, on some devices leaving little chance for a successful random pool init. True randomness is not that important here, so fix this issue by sticking to using /dev/urandom, like in older versions of this code.
