Hello, I'm trying to do an unattended CentOS 5.3 install. For the most part it's working. As of right now i'm statically assigning the machine an IP which i believe will allow %post to resolve names? I also like knowing where the box will show up. I am however having a few issues and I'm probably thinking to complicated on them. My first one is the fact that updates aren't working from %post. Under the assumption name resolution is working, see above with the static configuration, the issue is then most likely importing of gpg keys. I've got these lines in %post:
# GPG keys echo "Importing GPG keys ..." rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY* /usr/bin/yum -y update
When they're uncommented the box hangs, i'd love to see output.
---- I would expect to see that in the error out console <Control><Alt><F4> (I think...maybe F3, or F5, I always forget). Generally, I will log everything that happens anyway so I would add to each of the 'custom lines something like '>> post-install.log 2&>1' instead ----
My second issue is a cosmetic one. I want to set a standard prompt in /etc/bashrc. Out of the box the bashrc PS1 lines:
if [ "$PS1" ]; then [ "$PS1" = "\s-\v\$ " ] && PS1="[\u@\h \W]\$ "
I have to make changes to that second line so a sed substitution would probably be my best bet. I'm not sure how to grab the part i need and change it. Manually i change that line to:
PS1='\u@\h:\w$'
---- I find it's easier to just replace the whole file for this though you couuld use sed, I would probably just grab a copy of bashrc from an available web server and wget it it into place. ----
I'd like to get %post to do that for me. Next, i'd like to alter /boot/grub/grub.conf. I want to set it up for serial terminal support, so i have to add a serial and terminal lines at the top of the file say after any comment blocks that might or might not be there plus add console=tty0 and/or console=ttyS0,9600n8 to the append lines to however many kernels are there. Again, i'm assuming sed but i'm not sure how to get the parts i need and edit. I want to do other things, mostly with security, increasing password complexity requirements and pam, but that should be easy once i figure out how to alter the right sections in files. Any help appreciated.
---- sounds like you're too lazy to try sed to actually give us anything useful in terms of why it's not working. Google has millions of sed examples.
