Hello, commit 539618a0ddc2dc7f0fbe28de2ae0e07b34c81e60 Author: Lennart Poettering <lenn...@poettering.net> Date: Wed Oct 29 17:06:32 2014 +0100
util: make use of the new getrandom() syscall if it is available when
needing entropy
Doesn't require an fd, and could be a bit faster, so let's make use of
it, if it is available.
Beginning from this commit, switch root takes about a minute on my machine.

This line is pretty weird too, this commit is after v217 had been tagged.
