Typo or missing feature and a basic question
I'm new to grml so please excuse me if this on wrong list or similar.
Recently I've tried to install debian using grml and I found something that could be a typo: Line 136 of config file: # Run scripts from /etc/debootstrap/pre-scripts/ after setting up chroot. Shouldn't it state "/etc/debootstrap/scripts/" ?
In config file I've found extrapackages, but on the man page of grml-debootstrap there is no option extrapackages. Is this intentionally? This option is not implemented or simply not documented?
Additionally , I would be grateful for a help on how to use scripts from "scripts" direcotry. My plan was to add a script to compile a program (for instance dwm), however I was unable to achieve this. I'm unsure if this is feasible at all, and whether I'm positioned at the right directory (or how to check that). I invoked command with the -d flag: grml-debootstrap -d FILE
Finally, I have troubles at debugging debootstrap stages. If someone would show me how to do that, perhaps I could solve the previous problem by myself. I've read somewhere about install_notes file that could be used for this, but I haven't found much on it - assuming that I understood that correctly.
Thanks in advance.

You're pefectly right.

Yes, thank you. This typo was already fixed but did not yet make it into the stable repository. A new grml-debootstrap package is available in the grml-testing repository.

The man page lists /etc/debootstrap/extrapackages/ in the FILES section and describes its purpose. But there is no option to switch off installing extra packages. This is by intention. You can always set the variables before calling debootstrap, e.g.: EXTRAPACKAGES='no' grml-deboostrap ... (or just leave the extrapackages directory empty)

Scripts in the scripts directory are executed after the chroot was built and exited. I think you are looking for /etc/debootstrap/chroot-scripts/. Scripts in this directory are executed in the chroot, which is basically your new Debian installation.

You can have a look at grml-debootstrap itself, which is a shell script. There you're gonna see in which order the functions are called. I think in your case the relevant information is, that grml-debootstrap calls debootstrap to build a chroot and calls the script /etc/debootstrap/chroot-script which setups additional stuff in the chroot. So if you want to modidy your new Debian installation you should do it in the chroot. The other scripts are run before the chroot is created and after the scripts exits from the chroot. HTH

Ok. Consider that the chroot target directory is mounted ant /mnt/target/, and /mnt/config/ is a directory contianig configuration files, among others config file, and chroot-scrips/ directory. Now, let's invoke grml-debootstrap with -d flag, e.g. grml-debootstrap -d /mnt/config. Now, my root directory (/) is /mnt/target/ actually, so /mnt/config/ is unreachable, but nevertheless /mnt/config/chroot-scripts are still going to be invoked, right? However, I should not reference any file from /mnt/config in them, as anything there is unreachable. Therefore, (for example) to compile some source code I should copy relevant files from /mnt/config/ to /mnt/target/ in advance? Perhaps this could be done with pre-scripts? Did I get this right? It's not like /mnt/config passed with the -d flag is mounted (or copied) to /etc/debootstrap where the default configuration residues.
Finally, I have troubles at debugging debootstrap stages. If someone would show me how to do that, perhaps I could solve the previous problem by myself. I've read somewhere about install_notes file that could be used for this, but I haven't found much on it - assuming that I understood that correctly.

Yes, it helps. Thanks. In addition, I would ask is there a common way to log the output/error of the (grml-)debootstrap procedure, to see at which stage exactly a warning or an error occurred?

Yes, everything regarding those config files is copied to /mnt/target
However, I should not reference any file from /mnt/config in them, as anything there is unreachable. Therefore, (for example) to compile some source code I should copy relevant files from /mnt/config/ to /mnt/target/ in advance?
No, you don't need to (see below)
Perhaps this could be done with pre-scripts? Did I get this right? It's not like /mnt/config passed with the -d flag is mounted (or copied) to /etc/debootstrap where the default configuration residues.
Yes, it is, but not the whole directory. So you could put your files to the chroot-scripts directory or extra-packages directory and it will be copied to /mnt/target/etc/debootstrap/. You can also create directories like /etc/debootstrap/usr/local and they will be copied. Please have a look at the man page, section CUSTOMIZATION, to get more details.
Yes, it helps. Thanks. In addition, I would ask is there a common way to log the output/error of the (grml-)debootstrap procedure, to see at which stage exactly a warning or an error occurred?
I'm not sure if I understand your question correctly. You mean beside just piping the output to a file?
