タイムアウトによるストール/遅延を発生させずに、Qubes OS4.0の再起動/シャットダウン中に実行中のすべてのVMを安全にシャットダウンする方法は？（systemdの問題）
Qubes 4.0にも影響している issue が原因で、dom0からコンピューターを再起動またはシャットダウンすると、実行中のすべてのVMが最初にシャットダウンされない限り、アクションが完了するまで遅延（ストール）が発生します。 。
xfceの[ログアウト]メニューから再起動/シャットダウンを実行する前に、スクリプトを手動で実行してすべてのVMをシャットダウンする必要があります。そうしないと、ストールが発生する可能性があります少なくとも30秒続く可能性があります（ダウンした場合） DefaultTimeoutStopSecデフォルトの90sから30s）。
そのスクリプトと実行中のサンプル出力は次のとおりです。
[ctor@dom0 ~]$ cat preshutdown
#!/bin/bash
xl list
time qvm-shutdown --verbose --all --wait; ec="$?"
echo "exitcode: '$ec'"
time while xl list|grep -q -F '(null)'; do xl list;sleep 1; done
exit $ec

ただし、Dom0はFedora 25（Fedora 28はVMでのみ使用可能）でスタックしているため、systemdを簡単に更新することはできません（またはまだ方法がわかりません）-バージョン 231 = 240はgithubで最新ですが、それがsystemdの問題なのか、それともsystemdが試行する前に停止するように qubes-core.service を適切に変更する方法がわからないだけなのかわかりません。いくつかのDMデバイス。
this と this の回答を使用してみましたが、 result は変わりませんでした。
ストールしたときのsystemd出力の例を次に示します。

奇妙なことに、systemdで何も変更せずに、上記のストールが発生しました。最初の2回の再起動はストールではなく、3回目はストールでした。 （ 詳細はこちら ）
Qubes OS4.0で実行中のすべての実行中を安全にシャットダウンする方法VM 再起動/シャットダウン中？つまり、から再起動/シャットダウンする前に手動でスクリプトを実行する必要はありませんxfceメニュー。
考えられるアイデア：
ユーザーがログアウトしたときにタイムアウトするすべてのデバイスが停止している場合（session-2.scope？）、つまり、systemctl --user status *.deviceによって リストされている である場合はどうなりますか？優先される可能性がありますか？したがって、後者はqubes-core.serviceであるため、--systemが停止する前に常に停止します。どう思いますか？実行中（VMが実行されている状態でログイン）のsystemctl --userの内容は次のとおりです： https://Gist.github.com/constantoverride/a7dbad2146645387209b25e4c07de8ad#gistcomment-2701867
EDIT：--user service で試しましたが、すべてが一度に（つまり同時に）停止しているようですので、スクリプト上記は同時にタイムアウトします。
[〜＃〜] edit [〜＃〜]：方法がわからないか、systemdに停止する（そして停止を終了する）ように指示する方法がないことがわかりました）systemdがいくつかの--systemを停止しようとする前に、私の.deviceサービスが停止するため、私のサービスとそれらの.deviceの両方が同時に（90秒後に）タイムアウトして失敗します。ログを参照 ここ 。
問題は qubes-gui-dom0-4.0.8-1.29.fc25 by this code change（ this commit）。
したがって、 redsparrow 回避策はもう必要ありません。

Subject: [PATCH] xside: avoid making X11 calls in signal handler
This is very simlar fix to QubesOS/qubes-issues#1406
2148a00 "Do not make X11 requests in X11 error handler"
Since signals can be sent asynchronously at any time, it could also hit
processing another X11 message. For this reason, avoid making X11 calls
if exit() is called from signal handler.
Fixes QubesOS/qubes-issues#1581

これが行うことは許可することですqubes-guid（SIGTERMなどで）安全に終了するため、redsparrowからのSIGKILLは必要ありません。残りの情報については、redsparrow answer を参照してください。
After=dev-block-253:0.deviceを使用する必要はないと思います。これは、デバイスが/devに存在することを確認するためだけです。代わりにRequiresMountsFor=/my/mountpoint（ reference ）を使用してみてください。これにより、ファイルシステムが実際に正しい時間にマウント（およびアンマウント）されるようになります。
回避策 を見つけましたが、根本的な問題はまだ存在します（xfceから再起動（またはシャットダウン）を発行した後、*.devicesが他のすべてと同時に停止します。ログがあります ここ 使用したサービスファイルを含めます。これは、両方が同時にタイムアウトすることを示しています（90年代以降）。
回避策は次のとおりです。再起動/シャットダウンフェーズの早い段階でredsparrow.service（pkill -9 qubes-guidが必要です。pkill、つまりSIGTERMは実行しません）を行う別のサービス-9を用意します。これは、*.devices（/dev/dm-0など）の停止の試行と同時に実行されますが、pkillが配置されていない場合は、他の方法では実行されないqubes-core.serviceの前に実行されます。 、それらのデバイスの停止がタイムアウトになるまで（つまり、デフォルトでは90秒後）。 qubes-core.serviceは、preshutdownスクリプトを使用して実行中のすべてのVMのシャットダウンを実行するものですが、qubes-guidについて心配する必要はありません。
