Description Devon 2019-02-06 21:39:25 UTC

Description of problem:

Using nfs and have the same root, anaconda will fail to mount both bases and fail to install

Version-Release number of selected component (if applicable):

RHEL 8 nightly build

How reproducible:

Consistently

Steps to Reproduce:
1. Use an inst.ks and inst.repo path with the same root path.

BOOT_IMAGE=vmlinuz initrd=initrd.img inst.repo=nfs:nfsvers=4:10.12.212.245:/var/www/html/rhel8 inst.ks=nfs:10.12.212.245:/var/www/html/rhel8/rhel8.cfg inst.sshd


2. Install will fail with the following errors:

Actual results:

Fails to mount the inst.ks path as the inst.repo path is already mounted on the /run/install/repo/ path 

Expected results:

Anaconda would recognize the root path is already mounted and install correctly.
