Kubernetes won't start after upgrade to 22.02-RC.1-1

After upgrade to 22.02-RC.1-1 kubernetes server never starts after restart, the problem:

Nov 05 09:51:43 pingonas.lantech.int k3s[43656]: time="2021-11-05T09:51:43.827634849+01:00" level=fatal msg="starting kubernetes: invalid configuration: [unable to read client-cert /mnt/DATA1/ix-applications/k3s/server/tls/client-admin.crt for user due to open /mnt/DATA1/ix-applications/k3s/server/tls/client-admin.crt: no such file or directory, unable to read client-key /mnt/DATA1/ix-applications/k3s/server/tls/client-admin.key for user due to open /mnt/DATA1/ix-applications/k3s/server/tls/client-admin.key: no such file or directory, unable to read certificate-authority /mnt/DATA1/ix-applications/k3s/server/tls/server-ca.crt for local due to open /mnt/DATA1/ix-applications/k3s/server/tls/server-ca.crt: no such file or directory]"

The issue here is that "DATA1" was a pool which I migrated from and apps pool was selected there at first. I changed apps pool to "DATA" with data migration. That was on RC.1. After few reboots everything was warking fine, until upgrade to RC.1-1 when the issue above appeared out of nowhere.

My temporary solve is: mkdir /mnt/DATA1; cd /mnt/DATA1; ln -s ../DATA/ix-applications

Everything works after this.
