installonly_limit value not respected (removes running kernel)

[rlmenge]

Describe the bug

The installonly_limit value in tdnf.conf does not change the behavior of tdnf. Only 1 kernel and its modules are ever present. An upgrade/downgrade will remove all other kernels except the new kernel being installed. rpm -ihv and dnf install -y behave as expected,

ie. installonly_limit=3 should result in up to 3 kernels. However, all other kernels are always removed for the new kernel being installed.

This option is mentioned in the documentation in the example tdnf.conf and config code

Reproduction steps

# confirm installonly_limit=3
cat /etc/tdnf/tdnf.conf 

tdnf install -y kernel-<different version>

# check that running kernel vmlinuz has been removed
 ls /boot

# check that running kernel's modules have been removed (folder still present)
ls /lib/modules/$(uname -r)

Expected behavior

# confirm installonly_limit=3
cat /etc/tdnf/tdnf.conf 

tdnf install -y kernel-<different version>

# check that running kernel vmlinuz and new vmlinuz present
 ls /boot

Thank you for reporting.

Looks like, sadly, the option is not implemented at all.

Thanks for checking into this! Are there plans to implement installonly_limit in the future?
