Systemd truecrypt service no stdin

nasosnik · 2012-10-28 14:48:03

I have created a truecrypt unit according to the wiki, in order to mount an encrypted volume upon system boot. With initscripts i just used an entry at /etc/rc.local and /etc/rc.local.shutdown.

The problem is that the service starts as it should and prompts me for a password during boot, but it seems that it doesn't accept stdin from keyboard although i use the "StandardInput=tty-force" option. Any suggestions?

[Unit]
Description=Mount Truecrypt-encrypted filesystem
ConditionFileIsExecutable=/usr/bin/truecrypt
 
[Service]
Type=oneshot
ExecStart=/usr/bin/truecrypt -k "" --protect-hidden=no /path/to/file.tc /mount/point
StandardInput=tty-force
RemainAfterExit=yes
 
[Install]
WantedBy=multi-user.target

I don't know whether this helps, but systemd provides a program named systemd-ask-password. Maybe you should write a script using this.

I don't know why, but this script work son one of my Arch installs, and *not* on the other. The only real difference at that point would be the bootloader. You don't happen to be using grub-legacy?

Has anyone figured this out? I've tried the truecrypt service and truecrypt mount variations of systemd services from the Arch wiki with no success. I've been trying to test them from a terminal with no success. With the service variant, I named it truecrypt@.service and tried enabling via truecrypt@dev-sda4.service and it doesn't think there's such a file.

I also tried using ExecStartPre=systemd-ask-password "Please enter truecrypt password" as well as the same option for ExecStartPost and had no success.

Really would like this to work...

Re. the bootloader, I'm on grub legacy. I can try on my other computer, which is using syslinux.

I am indeed using grub-lagacy, but afaik it has nothing to do with stdin upon boot. Boot loader is responsible only for loading kernel into memory...

All I can say is that it works on my laptop which has grub2 installed. But perhaps the difference is not grub2, but the simple fact of the laptop's keyboard being connected via PS/2 and not USB like with my desktop (which has grub-legacy and where the input does NOT work).

Did anyone actually follow up the link falcondy provided? I noticed that the wiki still suggests a method which that thread recommends against (e.g. tty-force).

Natanji · 2012-11-12 10:13:36

I don't really know how to go without tty-force, since I have no clue how to use "systemd-ask-password" instead... some help would be greatly appreciated.

It works !
The important part is to modify fstab because it stops the boot process to let you type your password.
