configure network interface under chroot

[warron.french]

Because of the quick release of "Boot Hole" security patches for the kernel and other related packages I am in a situation where I need to reboot into Troubleshooting mode and mount /mnt/sysimage, configure the wlo1 (wireless networkk interface) under chroot.

There are no instructions to be found for configuring a network interface under chroot.

So can someone please provide all of the steps required to recover the OS due to the "Boot Hole" patches by yum undo, I cannot afford to lose some corporate data (I was wrong in my other post) on the laptop running CentOS 8 that I updated today - Thu, 30 JUL 2020 at roughly 700pm.

Thank you for the ordered steps.

Do you really have to config network in the chroot?

Doesn't the rescue OS config start/allow starting connections before you enter the chroot?

Well, let me tell you this.

Since I have started running CentOS 8 on bare metal, I have never seen a machine that required two reboots to recover networking after every even-numbered reboot. Weird right?

Anyway, when I rebooted into Troubleshooting/Rescue Mode my machine did not come up with an IP address. I am pretty sure that executing a yum undo still requires networking to reach out to the repositories successfully to re-implement the prior packages. Or am I incorrect?

I want to recover this laptop like the patches were never applied at all and maybe wait another week to attempt to update again.

What advice do you have?

Thank jlehtone,
