The subject says it all: I was trying to find out a short outline why one should use the one or the other.
As far as I can unsterstand it after a short evaluation is that both are able to do nearly the same. Both use debootstrap and are able to define hooks and afterwards a ISO is created.
The advantage of grml-live seems to be the usage of the FAI-class concept but debian-live seems to be the more "official" way to do it.
My motivation is a bit different than *-live and FAI provide. *-live are intended to build a Live-CD and FAI deploys a system on a running machine (by PXE or Boot-CD).
I do NOT need a bootable ISO. I need the possibility to install Debian into a USB-Device or CF-Card. So I actually use the base.tar.gz (created by FAI or by an other installation) to untar it onto the target from my running system. Afterwards again some hooks are run and the bootloader is installed. I think this is ridiculous! There must be a better way.
Any thoughts about this?
Allright, some thoughts about this. :)
You're right, "debian-live seems to be the more "official" way to do it" - that's its design goal. :) Whereas debian-live provides official Debian builds (like "does a plain Debian work on my system?"), grml-live focuses on user's (maybe very special) needs (like "i need a system which is specialised for the needs of sysadmins").
Notice that I'm biased as being the developer behind grml-live. ;) But I personally don't see the projects as competitors but instead I'm working together with upstream of debian-live on the underlying technologies so we share development wherever possible.
I personally *love* the class concept of FAI. It gives me a big and fast gun in combination with a swiss army knife so I can shoot on every problem that might arise. :)
Regarding your needs: "I need the possibility to install Debian into a USB-Device or CF-Card". Looking at the existing grml-technologies there are different approaches available:
* grml2usb: install a grml ISO on a given device * grml2hd: install a running grml system (nearly) 1:1 on a device * grml-debootstrap: install *plain* Debian on a device
Depending on your exact use case the approach of grml2usb/grml2hd might fit as well, though I think that either grml-debootstrap or your FAI/base.tar.gz solution fit better.
In a customer project I'm for example using grml-debootstrap for deploying Debian systems automatically, providing offline installation (no network access available), DRBD deployment, setup of SW-RAID, documentation of the hardware,...
But I guess you don't need all the fancy stuff overall, so if FAI/dirinstall works fine, you chose the right way already. And if you're not happy you can still consider switching to a different approach. ;)
Hope this helps.
