# My collection of systemd unit files
## vc-mounter.service / vc-mounter.rb
Mounts VeraCrypt volumes as a specified user (with sudo), runs fsck on them,
and executes an optional per volume custom ruby script.
## tmpfs-folders.service
A simple step towards read only root file system to save preciuos disk read/writes.
Mounts /var/log and user homes directories on tmpfs.
SETUP: create directory skeletons (see instructions in tmpfs-folders.sh)
## spindown-disks.service
Spind down disks before shutdown

## SETUP:
* `ln -f /opt/systemd-units/name.service /lib/systemd/system/` - **hard link it**
* `systemctl enable name.service`
* `systemctl daemon-reload` - **after some changes**

Note that `DefaultDependencies = true` implies:

* `Conflicts = shutdown.target `
* `Before = shutdown.target `
## [EARLY START](http://lists.freedesktop.org/archives/systemd-devel/2010-September/000225.html)
```ini
[Unit]
DefaultDependencies = no
Requires = sysinit.target local-fs.target
After = sysinit.target local-fs.target
Before = basic.target
[Install]
WantedBy = basic.target
```
## ONESHOTs: this combination stops the execution of both Start and Stop
```ini
Type = oneshot
RemainAfterExit = yes
```
## DEBUG E LOGS:
* `journalctl`
* `cat /var/log/boot.log`
* graphs:
* `systemd-analyze plot > boot-chart.svg `
* `systemd-analyze dot | dot -Tsvg > boot-full.svg `
* `systemd-analyze --order dot | dot -Tsvg > boot-order.svg `
* `systemd-analyze --require dot | dot -Tsvg > boot-require.svg`
