Subject: [PATCH] if hostname is not resolvable do not fail and use that
|
|
|
1070a0 |
hostname
|
|
|
1070a0 |
|

in commit 588756aa7aefc122310847d007becf3112647944 cobbler start using IP address in kickstart path due s390x
|
|
|
1070a0 |
but in BZ 253274 we have example where hostname is not resolvable from the location where cobbler run.
|
|
|
1070a0 |
But it is resolvable from location where client runs.
|
|
|
1070a0 |
So if cobbler is unable to resolve hostname, do not fail and revert to behaviour prior 588756aa7aefc122310847d007becf3112647944.
