so I have one older box that suffers from that. I installed haveged and seemed to went away: [ 1.600832] random: fast init done [ 2.417621] systemd[1]: systemd 240 running in system mode. (+PAM +AUDIT +SELINUX +IMA +APPARMOR +SMACK +SYSVINIT +UTMP +LIBCRYPTSETUP +GCRYPT +GNUTLS +ACL +XZ +LZ4 +SECCOMP +BLKID +ELFUTILS +KMOD -IDN2 +IDN -PCRE2 default-hierarchy=hybrid) [ 8.685406] random: crng init done So what is the advantage over using haveged? As far as I understand, it would reach the "init done" state before systemd took over, right? Sebastian
