Title: Remaster problems
Post by: georgp24 on November 10, 2013, 03:02:49 PM

I am remastering Core Linux using the "Remastering TC" page in the wiki. This is what I would call the manual approach. Due to having a hard-disk install with a multi-boot environment, EZremaster and Qremaster do not seem to work for me.

Anyhow, I end up with a CD that does boot and contains my applications. However, I have the following problems:

While Core Linux is loading the extensions I get these messages for each extension:
"tce-load: line 204 can't create /tmp/appserr: Permission denied"
"tce-load: line 302 can't create /tmp/setup.lst: Permission denied"

The extensions are loaded successfully in spite of that.

Also I cannot run my frame-buffer application. The problem can be reproduced with a copy command as well though:
When I enter "ls -l /dev/fb0" I get: crw-rw---- root root /dev/fb0".

But when I enter: "sudo cp /dev/fb0 ." I get: "cp can't open '/dev/fb0' No such device". My application also complains that it cannot open /dev/fb0.

However, if I do this copy on my hard disk installation I get a 5 MB file.

So what do I have to do to get that to work on my remastered CD?

The command "sudo wc /dev/fb0" still returns "device not found".

Are you sure you have a proper framebuffer console at boottime?

After endless tests and trying I found that this has nothing to do with my remaster but is also a feature of a stock Core 477 CD. So I post my question again in Core Q&A since I assume more people watch that forum.

I see 2 separate questions in OP of which a relation is not established.

I do not know if I understand your post correctly. The frame buffer problem seems to be solved using the tip from curaga.

The "Permission denied" messages did no longer appear when I used the "dynamic root fs remastering" method to make the bootable CD.

When starting over and using the manual method I got "Permission denied" messages for different files. So I have to explore that further. I suspect that I somehow modify the permissions and owner information when copying the files around on my disk before packing them again.

As suspected from the beginning, no relation between absent framebuffer vs. permission issues.

Yes, these were separate problems. Finally I got a working remastered CD now :)
