mklive - 'cosmetic' issue?

[dcung]

I have been using same laptop with most SSD spare space to make sets of ISOs collection.
I refreshed Bullseye, Bookworm, Daedalus sets yesterday.

I noticed something 'odd' during boot time. I presume that it happens on all of the build that I made yesterday, but I only tested about 6-8 of them (out of 30 or so ISOs). Only tested DDog, Jwm DE of Bullseye, Bookworm, Daedalus.

During boot time, it displayed 'wrong' kernel filename.
k-5.10.0-26-amd64.squashfs
k-6.1.0-15-amd64.squashfs

Functionally, they are working okay. Conky displayed correct kernel used too.

Anyone else notice this? or is it just my builds went wrong?

Another question - where can you find booting logs showing the screenshot? I looked in /var/log but could not find such info. This would save me taking fotos if I knew where to find the logs.

Is it related to this?

viewtopic.php?p=102681#p102681

So, with new build - I could not tell during boot time now due to truncation.
k-5.10.0-25-amd64.squashfs
k-5.10.0-26-amd64.squashfs
k-5.10.0-2x-amd64.squashfs

k-6.1.0-14-amd64.squashfs
k-6.1.0-15-amd64.squashfs
k-6.1.0-1x-amd64.squashfs

FYI - when I tried to rename kernel file to (I usually do this after nvidia driver update remaster - have not tested remaster yet)
00-k-5.10.0-26-amd64.squashfs

it displayed/complained some message about file numbering, etc, etc...but too fast for me without taking another foto.

Having read the whole thread, I know now that what I saw as 'odd' was related to this.
viewtopic.php?t=9736

Not sure that I like the change.
As in my frugal installation, unlike trister, I don't use many squashfs files.
The mklive default build, only has 2 squashfs files. I need no where near 100-140 squashfs files.

Now, at boot time, I find that I could not tell the exact kernel files due to truncation to accommodate that.

I have many frugal installations and it's nice to know what kernel files used during boot time.
So, I know which to update as it boots.

I guess, ultimately it is Fred's call.

Thanks, I will reconsider changing it, wanted to accommodate @trister's request and as it's indeed just a cosmetic change (as far as tested) I thought it couldn't do any harm.

@dcung Question:
I can easily change it so that the full .squashfs names are displayed at boot, but still the mountpoint names (in /mnt/live/memory/images) are truncated.
Would that be OK for you ?

That would be good, since I think the kernel squashfs file fullname provides useful info.

Hope that is easy modification. If it will take you too much effort, I can live with either.
Thanks Fred.

@dcung Yes, easy modification, did just one line edit, (like echo <fullname>.squashfs , really a cosmetic change only), so now when making new Bullseye, Bookworm or Sid build it will show full .squashfs names at boot (and as I said, the module mountpoints will still have the truncated names (as @trister requested)).

Also upgraded package "upgrade-kernel" (v1.14 now) reflecting this change.
For an existing build: If you want to create new initrd1.xz, install this new upgrade-kernel package and run the script '/usr/local/cr-initrd/mkinitrd' (part of upgrade-kernel package) from terminal .

Thanks again for your comment, I also like it much more with the full .squashfs names showing at boot.

@fredx181
I just made a couple of Bullseye iso.
The full .squashfs names showing at boot now.

Thanks Fred!

Very good job fred

I would just like to add a note here.
The problem was not the number of the squashfs files. It was the sum of their characters.
The same problem can occur even with just a few files with big filenames.. That is why I believe that this internal renaming works
To make things worse ,the error it produces doesn't help at all at determining the real problem.

Yeah, sum of their characters, right.
I don't understand what exactly you mean by (i.e. not sure if you still see a problem or not ?):

FYI - I tested latest Bullseye DDog build on one of my PC that has nvidia GTX670.
After installing nvidia driver and other customisation, I make a remaster as I usually do.
Remaster works fine.

Only thing I noticed is that the popup message showed truncated kernel filename.
No biggies. I just thought to report.

Sorry for late responce.

I mean that if you have 3 files with names :1.squashfs , 2.squashfs , 3.squashfs they have the same result in this issue as a single filename with the name : 123456789123456789012.squashfs

The problem is fixed with your modifications.
What I meant was that if someone didn't use the "truncated" names then when his filenames reach the maximum supported length his system will stop working without giving any clues.
