linux redhat + how to install only the latest kernel rpm under /boot

  • 772

installing of errata security kernel rpm ( from redhat sattelite ) on the linux red-hat,

could sometimes - create a diff 2-4 new update kernel under /boot ,

the problem here that /boot could be nearly %0 availbe space

is it possible to install only the latest rpm kernel and not all the previous kernels

I am not sure but I found the installonly_limit parameter from /etc/yum.conf

when we set installonly_limit=1 , does this mean to install always the latest kernel ?

for example

dose installonly_limit=1 ,

Tell us to keep to install only the higher rpm kernel release

and ignore installing the other old kernel version?

/etc/yum.conf 

installonly_limit=1
linux yum redhat kernel rhn

    No, it is not possible: yum intentionally manages kernel updates as new installation, rather than true upgrades.

    If your /boot partition is full, you should first remove oldest kernels (but not the one currently running - you can find it issuing uname -a) using yum remove. After that, you can install the newer kernels.
