From 770b5ce4fc31a336a41e81381c229da725ef0cfa Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Mon, 15 Jun 2015 19:24:43 +0200 Subject: tmpfiles: automatically remove old machine snapshots at boot Remove old temporary snapshots, but only at boot. Ideally we'd have "self-destroying" btrfs snapshots that go away if the last last reference to it does. To mimic a scheme like this at least remove the old snapshots on fresh boots, where we know they cannot be referenced anymore. Note that we actually remove all temporary files in /var/lib/machines/ at boot, which should be safe since the directory has defined semantics. In the root directory (where systemd-nspawn --ephemeral places snapshots) we are more strict, to avoid removing unrelated temporary files. This also splits out nspawn/container related tmpfiles bits into a new tmpfiles snippet to systemd-nspawn.conf --- Makefile.am | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'Makefile.am') diff --git a/Makefile.am b/Makefile.am index a2e8709e52..6ca303f6a4 100644 --- a/Makefile.am +++ b/Makefile.am @@ -2183,7 +2183,8 @@ dist_tmpfiles_DATA = \ tmpfiles.d/tmp.conf \ tmpfiles.d/x11.conf \ tmpfiles.d/var.conf \ - tmpfiles.d/home.conf + tmpfiles.d/home.conf \ + tmpfiles.d/systemd-nspawn.conf if HAVE_SYSV_COMPAT dist_tmpfiles_DATA += \ -- cgit v1.2.3-54-g00ecf
