The LVs generated by manual partitioning(clicking '+' to add partitions manually) are like:

There are mainly two kinds of differences:
1. For auto partitioning, the size of tmp is 1G, but for manual partitioning, it's 2G.

2. For auto partitioning, the name of partitions mounted on /var/log and /var/log/audit are var_log, and var_log_audit, respectively.
   For manual partitioning, they are var-log, and var-log-audit, which replaced the "_" with "-".

As in both auto partitioning mode and manual partitioning mode, the NIST LVs are generated by program, users can't specify them explicitly, so it's better to keep them consistent.


Version-Release number of selected component (if applicable):
redhat-virtualization-host-4.1-20170714.1


How reproducible:
100%


Steps to Reproduce:
1. Install redhat-virtualization-host-4.1-20170714.1 via Anaconda GUI, and choose auto partitioning, finish all needed steps.
2. Reboot and log into RHVH, run "lvs -a"
3. Reinstall redhat-virtualization-host-4.1-20170714.1 via Anaconda GUI, and choose manual partitioning, click "+" to add /boot, /var, /, and swap, finish all needed steps.
4. Reboot and log into RHVH, run "lvs -a"


Actual results:
1. The sizes of tmp are different, just as described above.
2. The names of partitions mounted on /var/log, /var/log/audit are different, just as described above.


Expected results:
1. The sizes of tmp could be the same.
2. The names of NIST LVs could keep consistent.


Additional info:
Comment 1 Yuval Turgeman 2017-07-18 13:45:46 UTC 
The /tmp size was already fixed on master (see https://gerrit.ovirt.org/#/c/75707/), and the naming issue is on POST in another patch (https://gerrit.ovirt.org/#/c/79565/)
Comment 2 Qin Yuan 2017-08-16 07:58:44 UTC 
Verify Versions:
redhat-virtualization-host-4.1-20170815.0
imgbased-0.9.43-0.1.el7ev.noarch

Verify Steps:
As the steps in comment #0

Results:
1. The size of /tmp is 1G, no matter choosing auto partitioning or manual partitioning.
2. The names of partitions mounted on /var/log, /var/log/audit are unified to var_log, var_log_audit, respectively.

So the bug is fixed, set the status to VERIFIED.
