From a2496c5de9af7e3ac3ef82a2257d14d8a0ac37fb Mon Sep 17 00:00:00 2001 From: Werner Fink Date: Thu, 19 Jul 2018 14:13:26 +0200 Subject: [PATCH] Implement a command mode and use it for chroot the current only known command is root= which enforce an already running haveged to switch by using chroot(2) to new root file system and to an execv(3) there to become rebased. This allows haveged to survive the switch root within initrd and hold the entropy at high level.
