Linbo imaging system for linuxmuster.net
23 stars 22 forks source link

start.conf exmaple use /vmlinuz as starting point but this link is not created in all modern distributions #142

Modern distributions (e.g. ubuntu 20.04,CentOS 7 )have stopped to create the symlink

/vmlinuz -> /boot/vmlinuz-<atcutal version number>

Same thing goes for initrd.img. So a Linbo Linux-Client configured with

 Kernel = vmlinuz
 Initrd=initrd.img

in start.conf will not boot unless the symlink is manually added. I propose to adapt linbo documentation and examples to use Kernel=boot/vmlinuz Initrd=boot/initrd.img instead so Linux will boot regardless of wether /vmlinuz-Symlink exists or not

one should add: the modern distribution started to create the symlink /boot/vmlinuz -> /boot/vmlinuz-<version> and stopped using the old location.

What if the /boot partition is separate? I'm not sure if having /boot on a separate partition from "/" worked for linbo up to now.

and one more: this is a transition time. several distribution in the linux client will still use /vmlinuz etc. I think linbo should not automatically search for /boot/vmlinuz or /vmlinuz although this would surely be easily possible.

So, how should we treat this now? Can you provide sample files?

i do not understand how this is related to my hint and proposition.

linbo does not search at all, it tries to start vmlinuz/initrd from the place where start.conf points it too. that is why i opened that issue, because my ubuntu stopped (**) working when i upgraded to 20.04 which does no longer provide the symlinks /vmlinuz and /initrd.img which was still config'ed in the start.conf i used (which descends from the start.conf exmaple-file for ubuntu).

and one more: this is a transition time. several distribution in the linux client will still use /vmlinuz etc.

i haven't looked up all distributions but as far as /boot is in general THE linux boot directory i would assume, that in general/boot/vmlinuz is the file and /vmlinuz is the symlink.

This is an example file taking from our active system.

These are the original start.conf samples from the 6.2 installation run through a search & replace to have boot/vmlinuz instead of vmlinuz and boot/initrd.img instead of initrd.img
