From 068dec2f6694da263147a5a7fbc5e6d30f7d1e0d Mon Sep 17 00:00:00 2001 From: Scott Moser Date: Thu, 20 Apr 2017 13:20:38 -0400 Subject: Fix growpart for some cases when booted with root=PARTUUID. Growing the root partition would fail in either of two cases: a.) if the device /dev/root existed b.) the kernel command line had upper case letters in PARTUUID= the kernel will accept upper case partuuid, but udev creates links with lower case. In that scenario, we need to adjust to a /dev/disk/by- with lower case. The fix here addresses that, and also fixes uuid similarly for the lowercase issue.
