PlopKexec 1.4.1 CD cannot find Linux
« on: September 23, 2016, 19:33:10 PM »
Hi,
I just downloaded ‘Point Linux 3.2' stable release w/MATE, full featured desktop.
It installed itself, along w/GRUB 2 onto a thumbdrive, that PlopKexec 1.4.1 CD reports:

Waiting for a drive with Linux. . .
No Linux has been found.


http://pointlinux.org/download.html?version=3.2&flavour=mate&suite=full&arch=32&direct=true

Q: Can any Plop Boot Manager variant boot this USB device on micro's that their BIOS can't?
Those micro's that can, function OK.
thx,
fritual
PS. PlopKexec 1.4.1 CD has always functioned OK, in the past.

Sounds like this distribution uses no standard directories for grub config file grub.cfg.
PlopKexec searches the directories listed here: https://www.plop.at/en/plopkexec/configfiles.html

Simply tell PlopKexec where to find the information it needs: its your turn to find the grub config file "grub.cfg" of this distribution, extract the kernel name, kernel path, initrd, boot parameters, whatever and create a plopkexec.cfg using this information.

If this is asking too much simply use another linux distribution, one you already checked for booting out of the box...

vesalocal,
Grub.cfg info needed for PlopKexec:

plopkexec.cfg sample:

LABEL Point Linux GNU/Linux
      MENU LABEL Point Linux GNU/Linux, with Linux 3.16.0-4-686-pae
      KERNEL /boot/vmlinuz-3.16.0-4-686-pae
      INITRD /boot/initrd.img-3.16.0-4-686-pae
      APPEND root=UUID=xxxxxxxxxxxxxxxxxxxxxxxxxxx ro  quiet splash

Suspect this is all the data needed by plopKexec.
Q: What's the command to decode disk UUID?

`ls -l  /dev/disk/by-uuid/` shows the UUID.

Use ls without pen drive, then insert the pen drive and list again. The additional UUID is the one of your pen drive.

Hello,

I am unsure if the installed version is different to the "Try without install" menu option from the ISO. The ISO works fine with PlopKexec. As alternative, just copy the content of the ISO to the USB drive.

Best regards
Elmar

Dear Elmar:
My conclusion to install was that distro lacks persistance.  Maybe you have a different perspective?
This is my first Debian install experience, requiring more focus than before.
Wishing you a happy day! :)

Hey Elmar & vesalocal!
Distro now boots w/PlopKexec:
Quote
lrwxrwxrwx 1 root root 10 Sep 28 08:31 d5e4b5a6-72ff-4826-8a9e-249a3562cabb -> ../../sdb1
. . . much quicker than grub
