[Bug 1783810] Re: [SRU] blocks boot on core18

[Sergio Cazzolato]

I validated this by using this new core18 image http://people.canonical.com/~mvo/tmp/core18-amd64-18-alpha20180803-with-lp1783810.img.xz
It is working now

Title:
  [SRU] blocks boot on core18

Status in util-linux package in Ubuntu:
  Fix Released
Status in util-linux source package in Bionic:
  Fix Released

Bug description:
  The current version of libuuid is using getrandom() without the
  GRND_NONBLOCK flag. This means that in early boot the boot is blocked
  until the crng is initialized to "level=1" which on virtual machines
  may take some time.

  Upstream fixed this in https://github.com/karelzak/util-
  linux/commit/a9cf659e0508c1f56813a7d74c64f67bbc962538 and we should
  just backport the fix.

  [Impact]
   * Makes systems that use libuuid in early boot hang

  [Test Case]
   * boot a fresh core18 system with kernel 4.15

  [Regression Potential]
   * little, change is very targeted

  This is uploaded to the bionic-proposed queue now.
