kickstart postinstall display

In a text, headless kick session, does anyone knows how to display output to the text screen? In a text-based but not headless, this works: echo "display to main screen" > /dev/tty in headless mode it doesn't seem to work. The output looks like this with nothing echoed from postinstall: ...

kvm guest installed via kickstart is setup with bridge

Does anyone know of an option in kickstart/anaconda that would prevent a bridge from being setup? Here's a scenerio that has been causing issues for me. On my kvmhost are two bridges, say bridge0 and bridge1. virt-install is used to a CentOS 6.4 guest, attaching two interfaces to bridge0 and bridge1...

Aligning partitions when doing parted

What's the best way to align partition in parted? I often get this error when scripting partition creation via parted. Warning: The resulting partition is not properly aligned for best performance. Given start and end in MiB, what's a good calculation one could do to properly select start and end? T...

star/ tar not saving extended attributes

star and tar (redhat/centos flavor) have the ability to save the extended attributes. However, this doesn't seem to work when transferred via a pipe. This works tar --xattrs -cvf test.tar dirtobackup # this saves into test.tar tar --xattrs -xvf test.ar # this extracts everything out of tar file agai...

WORM - write-once-read-many

I would like to get inputs on what would be a good option to create a WORM (or Write-Once-Read-Many) for files and directories? I'm aware of extended attributes (-i to chattr can do that) but that would be too slow since there are too many files (multi-millions). Plus, only root could use chattr -i ...

CentOS 5.7 and XFS file system

CentOS 5.7 doesn't include the user-land tools (mkfs.xfs) to create file system during kick. Furthermore, any modification to stage2.img renders it unusable. During installation, it errors with "The CentOS installation tree in that directory does not seem to match your boot media" if any change is m...

Re: Yum from vault.centos.org

Yeah, I figured that out afterwards to use base url. Yes, also aware of older releases potentially having more security problems. However, we tend not to upgrade since we have thousands of systems and it takes a long time for us to recertify our applications on the newer OS. We're also behind severa...

Yum from vault.centos.org

Is it possible to use yum from the older release in vault.centos.org? Currently, some of our servers are running CentOS 5.2 but we don't want to upgrade. I tried to change the URL to this but didn't work: [base] name=CentOS-$releasever - Base #mirrorlist=http://mirrorlist.centos.org/?release=$releas...

Re: interface swap still in CentOS 5.3?

Damn! I wasted a couple of hours. We rely on our server vendors to put the mac addresses on a label affixed to the server. I just found out they had the mac addresses swapped around on the label. Taught me to not trust anyone but to find out for myself. Consider this issue resolved. Thanks for your ...

kudzu is already off

# chkconfig --list kudzu
kudzu 0:off 1:off 2:off 3:off 4:off 5:off 6:off

We usually disable kudzu.
