We apaprently filled up /boot on a bunch of cluster workstations, and
users are helpfully getting notified about this. We need to clean it up.
I propose the following recovery hook. (Cluster workstations should only
have linux-image-generic). I plan to push this out on the 26th unless
people object. (I'm not here on the 21st, and, uh, that's a bad day to
push out additional things)
Silence will be interpreted as approval.
#!/bin/bash
kernels=$(dpkg-query -W -f '${Package}\n' linux-image-\*-generic | sed -e
's/^linux-image-//' | sort -V)
numkernels=$(echo "$kernels" | wc -l)
if [ $numkernels -le 2 ]; then
exit 0
fi
toremove=$(echo "$kernels" | head -$(($numkernels-2)))
kpkgs=
for k in $toremove; do
if [ "$(uname -r)" != "$k" ]; then
kpkgs="$kpkgs linux-image-$k"
fi
done
if apt-get -s remove $kpkgs; then
apt-get remove $kpkgs
fi
