I used to use grml2hd after booting off grml, but today I tried the grml2hd from the chroot. I think nobody has ever done this before. I'm just trying to see if I can get it working. If so, I could do the Grml HD installation then system customization from within my current system, so that I could have almost zero down time.
Nice idea! :)
Here are some issues/questions regarding grml2hd.
- I think the document (http://grml.org/grml2hd/grml2hd.html) is not up-to-date with the script. E.g., I didn't find the switch "--noninteractive" documented.
Thanks, I updated the docs (it's "-i"/GRML2HD_NONINTERACTIVE=1) according to what's shipped with grml.
- I saw that the script is trying to duplicate the whole /dev directory. Is this still necessary? -- this is not a question but a request for explanation, because I thought udev would take care of populating the /dev directory on the fly.
As we support a 'noudev' bootoption we want to make sure you always have a valid /dev present. It shouldn't hurt anyone this way.
- now to the issue of using grml2hd from the chroot itself. It didn't work for me. It almost failed to copy over anything:
cp: cannot stat `backups': No such file or directory cp: cannot stat `boot': No such file or directory cp: cannot stat `cdrom': No such file or directory cp: cannot stat `dev': No such file or directory cp: cannot stat `etc': No such file or directory cp: cannot stat `floppy': No such file or directory cp: cannot stat `home': No such file or directory cp: cannot stat `initrd': No such file or directory cp: cannot stat `lib': No such file or directory cp: cannot stat `media': No such file or directory cp: cannot stat `mnt': No such file or directory cp: cannot stat `none': No such file or directory cp: cannot stat `opt': No such file or directory cp: cannot stat `root': No such file or directory cp: cannot stat `sbin': No such file or directory cp: cannot stat `selinux': No such file or directory cp: cannot stat `swap': No such file or directory cp: cannot stat `usr': No such file or directory cp: cannot stat `var': No such file or directory
UTSL reveals that it might cause by the 1st line, "cd /UNIONFS", in the copy_files function. Can we do something about it? I mean do something to make it chroot friendly? Further, my currently grml was first grml2hd'ed from grml ver0.7, and there is no /UNIONFS mount point or directory in my current system. I guess I can't use grml2hd to dupe my currently grml to another HD as well, can I?
Yes, would be great to have a grml2hd version which could install grml directly from a chroot (so you don't have to boot it at all ;)). But currently I don't have the time to implement the relevant changes for grml2hd on my own. I welcome any patches of course - but if you want to see that implemented by myself you'd have to wait a little bit.
I've added it to our BTS (see http://bts.grml.org/grml/issue270) so we don't forget it.
