# complexity of what to do with a kernel after it is installed or removed

# is left to other scripts and packages: they can install scripts in the

# /etc/kernel/{pre,post}{inst,rm}.d/ directories (or an alternative location
|
||
|
|
# specified in KDEB_HOOKDIR) that will be called on package install and

||
|
|
# removal.
