Hello,
please find attached a very simple patch which allows consistent customization
of the coloring schemes of the emerg, notice, info and debug levels in dmesg.
(currently only alert, crit, err and warn coloring schemes could be customized).
output changes (when coloring enabled):
emerg level takes a default reverse+red, as alert and crit.
debug level takes dark gray (seems reasonable)
As my color choices might not suit the masses (or even offend them!),
notice and info levels are unaffected and keep a default reset vt100 sequence.
Afterall, they could then be customized via /etc/terminal-colors.d/dmesg.scheme
== LEGAL STUFF ==
Due to the triviality of the patch, I HEREBY EXPLICITELY DISMISS any right, copyrights, whatsoever,
applying to this patch, with or without changes, and grant the right to the maintainers, authors,
or whoever, to have it applied, even on his/her own name, without even mentioning me,
hoping this will make things faster and paperless, and useful to the community.
(If this is not sufficient or explicit enough, please tell, but, honestly...)
Regards, Thanks & Happy new year, if not too late.
