# Script for effectively collecting the core dump/dmesg from
# within a minimal initrd - part of the kdumpst tooling.
# The most fail-prone operations are guarded with conditionals to
# bail in case we indeed fail - worst thing here would be to have
# a bad condition and get stuck in this minimal initrd with no
# output for the user. Notice that the script is used in both
# dracut and initcpio cases.
#
#ENTRY POINT
# Bail out in case we don't have a vmcore, i.e. either we're not kdumping
# or something is pretty wrong and we wouldn't be able to progress.
VMCORE="/proc/vmcore"
if [ ! -f "$VMCORE" ]; then
reboot -f
fi
# We have a more controlled situation with regards the config
# files here, since we manually added them in the initrd and
# the validation also happened there, during such addition,
# hence not requiring checks here.
