This condition should be a unusual, but it's possible if users are installing kdumpst right after a kernel upgrade, without rebooting for example. To achieve this, just check if the modules dir exists. Signed-off-by: Guilherme G. Piccoli <gpiccoli@igalia.com>

# General comment of a caveat here: INITRD_installation() must be
|
|
# reentrant and only install the INITRD handlers if they're not
|
|
# already installed. This is necessary due to a kinda chicken-egg
|
|
# problem: the first time initramfs creation is attempted, we did't
|
|
# necessarily run the INITRD package installation hooks yet, hence
|
|
# we may be unable to properly create the initramfs image. "Easy"
|
|
# solution is to just try to install them always, it's cheap and not
|
|
# dependent of package install time magic.
|
|
|
|
# Parameter passing case - since this is invoked by the kdump-load
|
|
# script, we must be sure that the INITRD package is available.
