Under /boot we have the following files ( red-hat Linux version 6.6 )
cd /boot
# ls -ltr

Because /boot size is very small, (90M size)
We want to delete the previous kernel from /boot include ALL the other files that related to this kernel
The current running kernel version
# uname -r
2.6.32-573.12.1.el6.x86_64
So now I want to capture all the files that are not related to the current kernel , and can be deleted from the /boot
egrep -v will do the Job
# ls -ltr | egrep -v "2.6.32-573.12.1|lost\+found|grub|efi"

# rpm -qa | grep "2.6.32-504.30.3"
kernel-2.6.32-504.30.3.el6.x86_64
so my plan is to perform the following
Remove the previos kernel
rpm –e kernel-2.6.32-504.30.3.el6.x86_64
Remove the following files from /boot
rm config-2.6.32-504.30.3.el6.x86_64 rm System.map-2.6.32-504.30.3.el6.x86_64 rm symvers-2.6.32-504.30.3.el6.x86_64.gz rm initramfs-2.6.32-504.30.3.el6.x86_64.img
My question:
Is my plan is risky ? , or I can be sure that my procedure is safe ?
