Does fallback option work with BLS / Grub2 in CentOs 8

Post by starbearer » 2020/07/12 22:36:18

Wanted to try out recovery scenarios, including failed kernel upgrade causing boot freeze.

In CentOs 8, BLS is being used for specifying boot entries and I an not sure if fallback options will work.

I added -

Code: Select all

Timeout 20
Fallback 1
to my grub.cfg, rebuilt it but didn't have the desired effect. Some other sections advocate using panic instead.

Could someone illustrate how I might go about implementing a basic fallback mechanism in CentOs 8, if indeed it's still possible?

Would appreciate it. Thanks.
