  1. [all variants] Re: Will a manual "grub-install" ever be nuked by an `apt-get upgrade'?

    OldFred - that's helpful.

    As shown in the first two links:


    debconf-show grub-pc | grep "grub-pc/install_devices"
    shows which device was given to grub-install during installation, and that...
  2. [all variants] Re: Will a manual "grub-install" ever be nuked by an `apt-get upgrade'?

    Oldfred - please, you and I have already discussed this at the link in the footnote, and I have spent a fair bit of time on the grub forum. I know what I want to do here, and this is the correct way...
  3. [all variants] Will a manual "grub-install" ever be nuked by an `apt-get upgrade'?

    Hi all -


    I'd like to do a grub-install to a USB, with the first partition used for the /grub directory. That directory will include a grub.cfg that presents a menu with options to chainload a...
  4. [all variants] Re: What modules are available (& which do I need for RAID): /etc/initramfs-tools/mod

    Ok, here is a description of the issue of getting modules into the initramfs: https://wiki.ubuntu.com/Initramfs (Just search for the word "modules" in that page.)

    I think I've worked out that all...
  5. [all variants] Re: What modules are available (& which do I need for RAID): /etc/initramfs-tools/mod

    @MAFoElffen - Yes, you're on the right track, that's basically what I'm doing. Thing is, I do my disk-prep a little bit differently, and so the install doesn't figure out that it needs the crypt &...
  6. [SOLVED] Re: /boot on USB - One USB for Multiple Machines? - Possible?

    The proper approach is to install grub on the USB by hand, and use that to chain-load the core.img from the boot partition associated with the machine you want to boot. To identify which machine...
  7. [all variants] Re: What modules are available (& which do I need for RAID): /etc/initramfs-tools/mod

    @MAFoElffen - I really appreciate your reply. Thing is, perhaps everyone's reading far too much into my question. I understand cryptsetup and mdadm pretty well. What I'm doing is preparing my disk...
  8. [all variants] Re: What modules are available (& which do I need for RAID): /etc/initramfs-tools/mod

    @gordonintoranto - It's software raid under Ubuntu 14.04.

    Still, the question is also general. Where do I find a list of initramfs modules & how do I identify which ones are to be used for any...
  9. [all variants] What modules are available (& which do I need for RAID): /etc/initramfs-tools/modules

    Hi all. I've had to do some disk preparation before an install, and discovered that to get the system as I wanted it configured to boot, I had to add some modules to /etc/initramfs-tools/modules...
  10. [SOLVED] Re: /boot on USB - One USB for Multiple Machines? - Possible?

    This discussion is continuing, here:

  11. [SOLVED] Re: /boot on USB - One USB for Multiple Machines? - Possible?

    Again, I'm being a bit thick. The LUKS header has the UUID of the disk in it. If my cryptab identifies the disk by UUID, then choosing the wrong menu entry will end up with an initramfs that...
  12. [SOLVED] Re: /boot on USB - One USB for Multiple Machines? - Possible?

    *What I need to do here is in the initramfs, somehow add a check that I am looking at the right machine. Since I'm going to be unlocking a LUKS crypt, if the password is different then I'm fine since...
  13. [SOLVED] Re: /boot on USB - One USB for Multiple Machines? - Possible?

    This doesn't appear to be the case. Grub can install the images in any directory, using the --boot-directory option.


    Fine.


    I don't see this. Why?


    Ok, here's something else I'm not...
  14. [SOLVED] Re: /boot on USB - One USB for Multiple Machines? - Possible?

    @OldFred. Regarding your first response. I see you've taken this from an askubuntu question, but this doesn't get to my question. (And notice that --root-directory is an old option. It's now...
  15. [SOLVED] Re: /boot on USB - One USB for Multiple Machines? - Possible?

    Thanks guys, but I don't think you're getting to the issue, here. I'm going to propose an approach which might work. Let's just consider two installations with one USB stick.


    (1) USB is...
  16. [SOLVED] Re: /boot on USB - One USB for Multiple Machines? - Possible?

    Ok, @OldFred - Thanks for your input. Will have to study in detail tomorrow, but one question.


    Does this present any difficulty if the system is encrypted (as they all will be)? We can just...
  17. [SOLVED] Re: /boot on USB - One USB for Multiple Machines? - Possible?

    Thanks, Ian. You're saying there's no way to set this up so that it works with grub menu entries pointing to the various kernels/initramfs's, and grouped by machine?

    Alternatively, is there some...
  18. [SOLVED] Re: 14.04: Prepared Disk (LVM/LUKS/LVM), Installed. Reboots to BusyBox; Chroot Fix Fa

    I'm trying to build a RAID system now, but I'm unclear on which modules I'll need for that. I'm finding different lists, dm_mirror, dm_raid and dm_region_hash; or maybe just dm_raid and raid1. Can...
  19. [SOLVED] /boot on USB - One USB for Multiple Machines? - Possible?

    Hi all. I'm trying to build a few machines, each of which I would like to have /boot on a USB stick. I am wondering if it's possible to use a single USB for multiple machines? I have seen...
  20. [SOLVED] Re: 14.04: Prepared Disk (LVM/LUKS/LVM), Installed. Reboots to BusyBox; Chroot Fix Fa

    For anyone else who's looking at this, I'll add that there is one grub error that appears, but I can still boot with no problem:

  21. [SOLVED] Re: 14.04: Prepared Disk (LVM/LUKS/LVM), Installed. Reboots to BusyBox; Chroot Fix Fa

    It works!! Didn't need to run update-grub at all. Only update-initramfs, as you said. Only (stupid) error, caused by the fact that's is been so long since I looked at that partially installed...
  22. [SOLVED] Re: 14.04: Prepared Disk (LVM/LUKS/LVM), Installed. Reboots to BusyBox; Chroot Fix Fa

    Dude, I'm gonna try it. I thought it had something to do with BtrFS and had found long, tedious explanations of how to mix LUKS & BtrFS in a root volume. So, (for the moment) I had given up on the...

    [ubuntu] Re: access to HFS+

    I'm interested in this myself, if anyone's had any experience.

    Also, I'm not clear on the status of hfsprogs regarding >2TB disks and journaling for hfs+ volumes. Does anyone know?
  25. [SOLVED] 14.04: Prepared Disk (LVM/LUKS/LVM), Installed. Reboots to BusyBox; Chroot Fix Fails.

    Hey all - I prepared my disk & did an install of 14.04, but it fails on reboot @busybox. I tried repairs using chroot, but that fails at grub-probe. I'd be grateful for help on either step.
