Remove unused kernels
Outdated kernels are using too much disk space on the boot partition.
You can check the current used kernel with:
uname -r
You can check all kernel versions installed with:
ls /boot | grep vmlinuz | cut -d'-' -f2,3
You may check all kernel dependencies with:
dpkg -l | grep ^ii | grep 2.6.24-30 | awk -F' ' '{ print $2 }'
