I'm new in using IMA with a TPM. Is there somewhere a good tutorial from the installation to the use ? 
I have a ubuntu version 9.04 with a kernel 2.6.28. I didn't find any patch for that kernel on sourceforge, do I need to compile a more recent kernel like 2.6.30 that has the IMA option ?
Do I need TrustedGrub to have IMA ? In that case it will only work with grub1 and not grub2 right ?

Thanks for looking
