Big but self-explanatory commit: rename the tool. The name choice was kdumpst, since it's a tool to enable both kdump and pstore setting, also it's a silly wordplay with the superlative of kdump, as in "kdumpest". It's an invasive change (touches most of the files), but should offer no functional change other than logging messages showing kdumpst now, instead of kdump, and some filenames. Notice it doesn't touch documentation, which will be done in a subsequent commit. Signed-off-by: Guilherme G. Piccoli <gpiccoli@igalia.com>

# 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.

# 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.
