Description of problem:
There were no devel results in rebase bug 1771584 so I'm not sure if I'm even using this command's new feature correctly, but according to that report, automatic --uname-pattern for Red Hat distributions should now work instead of the user providing it manually.


[root@hayes-02 ~]# uname -ar
Linux hayes-02.lab.msp.redhat.com 4.18.0-190.el8.x86_64 #1 SMP Wed Mar 18 09:34:40 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

# this is what I would have now expected to work. 
[root@hayes-02 ~]#  boom profile create --from-host 
Could not determine uname pattern for 'Red Hat Enterprise Linux'

# now I tried to add each required argument one at a time to see if anything was gathered automatically
[root@hayes-02 ~]# boom profile create
profile create requires --name
[root@hayes-02 ~]# boom profile create --name "Red Hat Enterprise Linux"
profile create requires --short-name
[root@hayes-02 ~]# boom profile create --name "Red Hat Enterprise Linux" --short-name rhel
profile create requires --os-version
[root@hayes-02 ~]# boom profile create --name "Red Hat Enterprise Linux" --short-name rhel --from-host
Could not determine uname pattern for 'Red Hat Enterprise Linux'
[root@hayes-02 ~]# boom profile create --name "Red Hat Enterprise Linux" --short-name rhel --os-version 8.2
profile create requires --os-version-id
[root@hayes-02 ~]# boom profile create --name "Red Hat Enterprise Linux" --short-name rhel --os-version 8.2 --os-version-id 8.2

# in the end, the profile appeared to need to be created the exact same way it did in past releases.
[root@hayes-02 ~]#  boom profile create --from-host --uname-pattern el8
