From 0948562c326150635501cf6d255b318c35e8ca9a Mon Sep 17 00:00:00 2001 From: Joseph Kogut Date: Fri, 12 Jun 2020 10:40:29 -0700 Subject: [PATCH] package/earlyoom: new package EarlyOOM daemon for triggering Linux OOM killer before running out of memory, avoiding situations where the machine becomes unresponsive from out of control swapping. Some desktop distributions are installing and enabling this daemon by default to prevent unresponsive machines in OOM scenarios. https://fedoraproject.org/wiki/Changes/EnableEarlyoom Signed-off-by: Joseph Kogut [yann.morin.1998@free.fr: two spaces in hash file] Signed-off-by: Yann E.
