-# xcache service unit
-
-Show status
-
-```bash
-systemctl status systemd-nspawn@xcache
-```
-
-Restart
-
-```bash
-systemctl restart systemd-nspawn@xcache
-```
-
-Show logs
-
-```bash
-journalctl -eu systemd-nspawn@xcache [--since ...]
-```
-
-# container commands
-
-get a shell as xrootd user in a new temporary container using the xcache image
-
-```bash
-systemd-nspawn --keep-unit --register=no -M xcache /bin/bash
-```
-
-`/bin/bash` can also be replaced by an arbitrary command to be run. Pass `-u root` to get a root shell inside the container.
-
-To run an image other than `/var/lib/machines/xcache` additional options have to be passed on the command line since it won't read `/etc/systemd/nspawn/xcache.nspawn` then, e.g.
-
-```bash
-systemd-nspawn --volatile=overlay --register=no --private-users=655360 -u xrootd -D /var/lib/machines/<some-other-image> <some-command>
-```
-
-To get a shell in the **running** xcache container (as root, usually not nescessary)
-
-```
-nsenter --target=$(machinectl show --property Leader xcache | sed "s/^Leader=//")  --all
-```
-
-inside, one can then switch to a shell as the xrootd user with e.g.
-
-```
-su -s /bin/bash xrootd
-```
-
-# Manually delete files from cache
-
-This needs to be done inside the running container since it may need to clean up rucio metalink files from `dev/shm` which is currently a directory inside the container (not bind mounted).
-
-So, as root do
-
-```bash
-nsenter --target=$(machinectl show --property Leader xcache | sed "s/^Leader=//")  --all
-```
-
-And then
-
-```bash
-/var/local/xcache/rm_cached_file.sh <pattern>
-# e.g. to delete all files starting with AOD.05536542
-/var/local/xcache/rm_cached_file.sh AOD.05536542
-# or all files in the mc15_13TeV scope
-/var/local/xcache/rm_cached_file.sh mc15_13TeV
