Hello, Simon Eisenmann [2016-02-08 13:21 +0100]: > Yes it would be good to have rngd running from the initrd. Though as it > is a daemon, does it then need to be restarted when rootfs takes over?
It's recommended to stop/restart after pivoting, yes. Things started from the initrd link to the libraries (like libc6) in the initrd, thus you keep duplicate libraries in memory (libc from initrd and libc from the real OS. Depending on what the program does it might have more fds open to files which will go away when pivoting into the real root. This potentially leads to not being able to unmount/free the initrd. This should be okay for a program like rngd which only reads from /sys or ioctls and writes into /dev, as these are indeed transitioned over from the initrd. But you need to verify that it indeed does not have anything else open. Martin -- Martin Pitt | http://www.piware.de Ubuntu Developer (www.ubuntu.com) | Debian Developer (www.debian.org)
