Identify Ubuntu running in Live mode

sfxpt · 08-25-2010, 10:53 PM

Hi,

Is there any sure-fire way to identify whether the current Ubuntu system is running in Live mode or not?

I want to distinguish between Live mode and running from installed HD, and do some processing in boot up script.

Please help.

FYI, in grml, the /etc/grml_cd file only exit in Live mode file system; no such file if running from installed HD.

Thanks

Just look at the username in the top right corner of the screen: If it says 'ubuntu', that's the Live CD user account, which is Live CD specific.

Ops, thought that's good enough, but on second thought,
I want to do some processing in boot up script, which is before any user log on into the system.

Any other way?
thanks

Isn't that your answer then?

Code:

if [ -f /etc/grml_cd ] then runninglivecd=true

If that file doesn't work or exist for ubuntu then find another one that does (maybe by checking for a file on the mounted CD itself?)
