Description Greg Retkowski 2005-01-07 01:11:57 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5)
Gecko/20041107 Firefox/1.0

Description of problem:
If kickstarting with a kickstart config file referenced via NFS to a
hostname which is actually a cname in DNS, anaconda will crash with an
un-useful error message "install exited abnormally"



Then using a syslinx config such as ...
default ks
label ks
  kernel vmlinuz-rhws-3
append initrd=initrd.img-rhws-3 text load_ramdisk=1 network
ks=nfs:a-cname:/kickstarts/generic-rhws3-ks.cfg
...


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


How reproducible:
Always

Steps to Reproduce:
set up a cname for your kickstart server in DNS, something like:
filer-cname IN CNAME real-filer-hostname
Then when booting on the system to be kickstarted enter the argument
at the boot prompt:
linux ks=nfs:filer-cname:/kickstarts/generic-rhws3-ks.cfg


Actual Results:  After configuring an IP address (via DHCP) and
attempts to retrieve the kickstart config file the system displays
"install exected abnormally" and then halts.

Expected Results:  The system should either properly resolve the CNAME
and retrieve the kickstart config file, or display an error message
that CNAME's are not supported for retrieving kickstart configuration
files.

Are you sure the NFS server is running on the NFS server?  I do this all the
time with our internal servers without problems.

Also, what update release of RHEL 3 is this with?

Comment 2 Greg Retkowski 2005-01-07 19:13:50 UTC

Changing the 'ks=' entry to reference the IP address of the NFS server the
kickstart installation completes without error. nslookups of the CNAME resolve
the address correctly.

from /etc/redhat-release
Red Hat Enterprise Linux WS release 3 (Taroon Update 3)
