Public bug reported: 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. ** Affects: util-linux (Ubuntu) Importance: Undecided Status: Fix Released ** Affects: util-linux (Ubuntu Bionic) Importance: Undecided Status: New ** Also affects: util-linux (Ubuntu Bionic) Importance: Undecided Status: New ** Changed in: util-linux (Ubuntu) Status: New => Fix Released ** Description changed: The current version of libuuid is using getrandom() without the GRND_NONBLOCK flag.
