Re: Making a customized bootable ISO

Ah I didn't read that correctly. I've never done it but doing a quick search it looks like you can mount the LiveCD and modify the squashfs file. This tutorial seems pretty decent https://www.youtube.com/watch?v=_LobCfU_uIY

Re: Making a customized bootable ISO

I had to do this since at my work we have tons of air-gapped systems that ansible can't reach. I copied the default installer ISO to my system, put an edited kickstart file in the isolinux directory of the ISO, and then edited grub.conf and EFI/BOOT/grub.cfg to have a custom line that points to the ...

Re: What do you think of the recent Red Hat announcement about CentOS Linux/Stream?

Semantics aside, Stream is different from what CentOS was and what its userbase used it for - a compatible free version of the current RHEL version. As for RHEL allowing free production licenses now, how long until they pull the rug out? After CentOS 8's EOL jumped forward 9 years I have no faith in...

Re: UEFI with kickstart

I did this using xorriso. In the kickstart, I had to include a %pre section that checks if the system is uefi and add a /boot/efi partition if it is. The labelling is also very picky and it caused me a bit of a headache figuring out so make sure the version you're using is 8-1-1911. %pre check is: i...

Re: CentOS HAS BEEN CANCELLED !!!

RedHat still has to release their source though right? Wonder if another group will pick it up to keep a functional equivalent of the current RHEL alive.

Re: Binary content after aide --check to mail

I use almost the exact same line (yay STIGs) in my systems and I get the aide --check results in root's mail. My crontab has:

00 2 * * * root /usr/sbin/aide --check | /bin/mail -s "$(hostname) - AIDE Integrity Check" root@localhost

Re: How to run a script on CentOS Startup?

I advise against this, but why not set SELinux to permissive all the time instead of setting SELinux to permissive through a command every boot?

Re: how i add route

I usually use nmcli to add routes. Command would be: nmcli c m NIC +ipv4.routes "destination/subnet gateway" example: nmcli c m ens33 +ipv4.routes "192.168.10.0/24 192.168.1.254" A few notes, if you're routing to a specific address you don't need to add the subnet and if you want to replace routes r...

Re: How to check errors on boot?

I usually check dmesg and logs in /var/log/, or run journalctl with various flags. Mostly I start with what changed before the system booted to emergency so I have a general idea of where to look though.
