Description jan vestby 2005-12-30 12:40:33 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (compatible; Konqueror/3.5) KHTML/3.5.0 (like Gecko)

Description of problem:
setting the onlyn to e.g 5 result in installation of 4 kernels. On  
installation of the 5th every already installed kernel but the running kernel  
in removed.  
I think this is due to the design of the break condition in the 
postresolve_hook function in installonlyn.  
The variable numleft will already be 0 before decrementing when on 
installation of the last kernel of the preselected set size. 

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. set to_keep=4 (/etc/yum/pluginconf.d/installonlyn.conf) 
2. install a kernel (no 1, in adition to the running kernel)  
3. install a kernel (no 2)  
4. install a kernel (no 3)  

Actual Results:  Only 2 kernels are installed (the running + the newest) 

Expected Results:  The preset to_keep number of kernels present: only the oldest dropped   
when the "desired" count would have been exceeded.  

Additional info:

reproducibility: this happens on istallation of every (n-1)'th kernel (with  
to_keep=n) - if I got the arithmetic right.

Bump.  This bug is still present in yum-2.5.1-5 .
My /etc/yum/pluginconf.d/installonlyn.conf contains:

    # this sets the number of package versions which are kept

Today's rawhide update would have wiped out all my backup kernels.

Sorry, that "enabled=0" line should have read "enabled=1".
I cut 'n pasted the file that I modified to let yum run
the update without losing my kernels.

Hah, dumb bug.  Fixed in CVS, will be in 2.5.3-2
