Ubuntu preseed gotcha

[mpadams]

A snippet from my finally-working preseed command to run a "postinstall". btw, this works on Lucid 10.04

The "working command" from Debian+Ubuntu (semicolon missing on end)


#d-i preseed/late_command string apt-install zsh; in-target chsh -s /bin/zsh

What works on my setup (separated commands + semicolons)


d-i preseed/late_command string \
. /hd-media/dumpinstall.sh ; \
in-target sh /postinstall/postinstall.sh ;

*Working preseed I found that helped (http://www.unix.com/unix-advanced-expert-users/81346-running-script-after-preseed-install.html)
*Cross-posted blog post (http://unquietwiki.blogspot.com/2010/04/solved-ubuntu-debian-preseed-problem.html)
