Hi all,
I'm trying to use anaconda to build system images for Amazon's EC2
service. For this, you need to build a standard Linux system, then run
a tool to package up the system into several files.
The whole image building and packaging process is a bit adhoc, so I'm
trying to automate it. My idea is to start with a kickstart file, then
have anaconda build the system into a directory (rather than build a
system from scratch), then run the packager on that directory only. To
summarise:
kickstart file -> [anaconda install] -> full system image in a
directory -> [EC2 packager] -> final system image
Looking at various websites, the --rootpath option seems to be the answer.
On a CentOS 5.2 i386 machine, with the 11.1.2.113-1.el5.centos.2
version of anaconda installed, I tried this:
mkdir -p /mnt/runtime/usr/sbin/
LANG=en /usr/sbin/anaconda -T -m
http://mirrors.dedipower.com/centos/5.2/os/i386/
--rootpath=/root/buildroot
The installer displays the text menu, asks for the early options, but
then dies just after the "Checking dependencies in packages selected
for installation..." step:
Traceback (most recent call first):
File "/usr/lib/anaconda/urlinstall.py", line 95, in systemMounted
self.loopbackFile = "%s%s%s" % (chroot,
File "/usr/lib/anaconda/yuminstall.py", line 1328, in doPreInstall
if self.method.systemMounted (anaconda.id.fsset, anaconda.rootPath):
File "/usr/lib/anaconda/backend.py", line 180, in doPreInstall
anaconda.backend.doPreInstall(anaconda)
++ File "/usr/lib/anaconda/dispatch.py", line 201, in moveStep
rc = stepFunc(self.anaconda)

anaconda.dispatch.gotoNext()
File "/usr/sbin/anaconda", line 982, in ?
anaconda.intf.run(anaconda)
IndexError: list index out of range
The last statement run is:
self.loopbackFile = "%s%s%s" % (chroot,
fsset.filesystemSpace(chroot)[0][0],
"/rhinstall-stage2.img")
With this being the problem:
(Pdb) print fsset.filesystemSpace(chroot)
[]
The same problem has been noted before:
http://www.linux-archive.org/centos/101098-anaconda-test-problem.html
http://www.linuxsir.org/bbs/thread330760.html
Does anyone have any ideas?
Tom,
I think that anaconda is the wrong tool for your task. I think you
should look at using the "yum" command with the "--installroot" option.
What you want sounds similar to how a livecd is built.
Take a look at this for an example:

You also might want to look at revisor. It's a tool to automate the
creation of livecd's.
