From 304b3079a2039971db6d89f4557931776b758e41 Mon Sep 17 00:00:00 2001 From: Dimitri John Ledkov Date: Fri, 15 May 2015 11:44:22 +0100 Subject: core: Execute first boot presets in an enable-only preset-mode. This means any existing enabled units well be preserved and no pre-created symlinks will be removed. This is done on first boot, when the assumption is that /etc is not populated at all (no machine-id setup). For minimal containers that gives a significant first boot speed up, approximately ~20ms / ~16% in my trials. --- src/core/main.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src') diff --git a/src/core/main.c b/src/core/main.c index 08e84d8304..c39815b106 100644 --- a/src/core/main.c +++ b/src/core/main.c @@ -1618,7 +1618,7 @@ int main(int argc, char *argv[]) { bump_rlimit_nofile(&saved_rlimit_nofile); if (empty_etc) { - r = unit_file_preset_all(UNIT_FILE_SYSTEM, false, NULL, UNIT_FILE_PRESET_FULL, false, NULL, 0); + r = unit_file_preset_all(UNIT_FILE_SYSTEM, false, NULL, UNIT_FILE_PRESET_ENABLE_ONLY, false, NULL, 0); if (r < 0) log_warning_errno(r, "Failed to populate /etc with preset unit settings, ignoring: %m"); else -- cgit v1.2.3-54-g00ecf
