Lock Upgrade to a Specific Kernel

[ehowton]

To "lock" packages, use zypper "add lock"

zypper al 'kernel*'

Now you can run zypper -n update -t patch && zypper update -t patch
or
zypper up/zypper migration
All the while locking the kernel-level. You can verify lock with "list lock"

zypper ll 'kernel*'

# | Name | Type | Repository
--+---------+---------+-----------
1 | kernel* | package | (any)

Similarly "remove lock"

zypper rl 'kernel*'

When updating/migrating will likely get a list of applicable kernel combinations:
