## 5. Zram 

```
echo "zram" > /etc/modules-load.d/zram.conf
echo "options zram num_devices=1" > /etc/modprobe.d/zram.conf
echo 'KERNEL=="zram0", ATTR{disksize}="4G",TAG+="systemd"' > /etc/udev/rules.d/99-zram.rules
```

Create `/etc/systemd/system/zram.service` containing this:

```
[Unit]
Description=Swap with zram
After=multi-user.target

[Service]
Type=oneshot 
RemainAfterExit=true
ExecStartPre=/sbin/mkswap /dev/zram0
ExecStart=/sbin/swapon /dev/zram0
ExecStop=/sbin/swapoff /dev/zram0

[Install]
WantedBy=multi-user.target
```

Let Zram start on next boot:

	sudo systemctl enable zram

And reboot the machine.

## 6. BOINC

install via apt

```
sudo apt install boinc-client
sudo systemctl enable --now boinc-client
```

## 7. CernVM-FS

install from CERN repos

```
wget https://ecsft.cern.ch/dist/cvmfs/cvmfs-release/cvmfs-release-latest_all.deb
sudo dpkg -i cvmfs-release-latest_all.deb
rm -f cvmfs-release-latest_all.deb
sudo apt-get update
sudo apt-get install cvmfs
sudo cvmfs_config setup
```

Put these in `/etc/cvmfs/default.local`, since we don't have a proxy

```
CVMFS_REPOSITORIES=atlas.cern.ch,atlas-condb.cern.ch,grid.cern.ch
CVMFS_CLIENT_PROFILE=single
```

Test with

```
cvmfs_config probe
```
