This week, I received a message from one of our commercial ISP/Cloud
Hosting Providers, saying:
Unlike other Linux distributions, Ubuntu does not automatically
remove older, unused kernel packages after an update. Over time,
this will fill the boot partition and result in future updates
failing.
The email continued, recommending that we clean up old Ubuntu kernels
using this command:
# dpkg --get-selections|grep 'linux-image*'|awk '{print $1}'|egrep
-v "linux-image-$(uname -r)|linux-image-generic" |while read n;do
apt-get -y remove $n;done
Truly, I connected to several of my Ubuntu servers, some of which
have
been running for over 4 years, and I manually purged 3GB+ of old
kernels on some machines!
[...]
So I guess my questions are:
1) Surely we're not the only Ubuntu users whose /boot or root
partition has filled up with age-old kernels, are we?
Nope. I have the same problem. I'm managing a couple of LTSP servers
(with 10.04 LTS on them) and I saved around 400MB on the compressed
image file after I purged all the kernels and reinstalled the last one
(and deleted a lot of generated nbi.img files which remained after
purging the kernels).
There are also old linux-headers-* packages which can take up a lot of
space.
