== screen retten ==
<pre><nowiki>[21:25:35] <blotter> lsof -p <pid-vom-screen>
[21:25:58] <blotter> cd  /run/screen/S-root/; touch 4300.blackhole;  mount --bind /proc/4300/fd/3 4300.blackhole
[21:26:37] <blotter> 4300.blackhole dann durch die infos von lsof ersetzten
[21:26:44] <blotter> danach screen -x oder -r
</nowiki></pre>

Oder [http://git.savannah.gnu.org/cgit/screen.git/tree/src/README#n95 einfach SIGCHLD schicken]

z.B. bei Protokollupgrade (1.8 < 1.9) <code>tmux attach protocol version mismatch (client 8, server 7)</code>

<source lang="bash">
pgrep tmux
/proc/<TMUX_PID>/exe attach
</source>

== btrfs daily snapshots ==
<source lang="bash">/btrfs-admin/btrfs_snap_daily_lxc.sh</source>
oder
<source lang="bash">btrfs subvolume snapshot /btrfs/CONTAINER /btrfs/CONTAINER-snap-`date -u +%Y.%m.%d-%H.%M.%S`</source>
