This patch main goal is to "un-Debianize" the configuration file for kdump-steamos - thanks Emil (@xexaxo) for the discussions; it is with a bit of a heavy heart I do that, but let's comply with the modern distros ;-) We hereby put the config file in a more standard path: /usr/share. Usually users could override that with /etc/ file, but not in this case, or at least, not for now. Kdump/pstore is expected to work quietly, with no users' interference. Advanced users might want to play with the configs though; and those can just go ahead and edit the /usr/share/kdump/kdump.conf - it's all documented in the README. In the future we can improve that by having the override mechanism with the /etc file, let's see if we have a demand for that. Signed-off-by: Guilherme G. Piccoli <gpiccoli@igalia.com>

# Mount-related options - the DEVNODE points to the /home directory link;

# this is used to derive the numerical devnode for kdump, since the link

|
# is not present so early in the system boot. The KDUMP_FOLDER will be
|
|
# created if doesn't exist. The KDUMP_MNT is just a temporary file that

# Kdump controlling settings - for now we don't have network/iscsi dumps, only

|
# local storage dumps. If FULL_COREDUMP is !=0, we collect a full compressed
|
|
# vmcore, which might require a lot of disk space. The *_CMD settings refer
|
|
# to tunings on makedumpfile - we rely on zstd compression and maximum page
|
|
# exclusion for the full vmcore, mimic'ing Debian kdump. Finally, GRUB_AUTOSET
|
|
# determines if kdump-steamos should try to automatically set grub.cfg in
|
|
# order to reserve memory for kdump (if needed, i.e., when pstore is not in
|
|
# use) - keep it as '1' for enabling the mechanism (this is the default).
