rolling linux-source fix and a question about Slitaz's kernel

EDIT: my first fix doesn't fix , removed to not make you screw up your system following it

and now the question.

i have rolling with the recent kernel upgrade, so i have two kernel installed and i suppose to have two different output from the [c]uname -r[/c] command depending from if i boot one kernel or the other one and i should have two different /lib/modules/$(uname -a)/ dirs. uname give me the same output with both kernel and i have just one /lib/modules/ subdir.

i installed in a virtual machine a kernel built from linux-source and all goes as i've always seen, two uname output and two different /lib/modules/ subdir.

it this behavior a feature (and i would like to know the reason why, no criticism here) or someone should debug linux receipt?

Re: rolling linux-source fix and a question about Slitaz's kernel

how do i do this:

[c]xzcat /home/slitaz/src/linux-3.2.tar.xz  | tar x --strip-components=1[/c]

with busybox's tar or any other busybox's util?

could anybody help me with the "uname give me the same output with both kernel and i have just one /lib/modules/ subdir" question?

thanks

You can't. Install the xz package to get the xzcat command. For a package builder, make it one of the build dependencies. You may also need the real tar command for it to work.

Re: rolling linux-source fix and a question about Slitaz's kernel

Thanks for your answer.

i'm tryng to fix get-linux-source script, it's already broken so i probably would not break it more :-) .

Xzcat is in busybox:

[c]root@sltvaio:/home/fabio# ls -l $(which xzcat)
lrwxrwxrwx    1 root     root            17 Jan 21 13:49 /usr/bin/xzcat -> ../../bin/busybox[/c]
what i miss is the --strip-components in tar.

Would it be ugly to make the get-linux-source script check for presence of gnu tar and silently install it - use it - remove it if it was not present?

I wouldn't put it as a dep in receipt because it's only required to run the

[c]xzcat /home/slitaz/src/linux-3.2.tar.xz | tar x --strip-components=1[/c]

command, having another command which extraxt a tar stripping the first leading dir would do the job, but i can't find out how to do it.

btw, do you know why in cooking every minor kernel upgrade should put modules in /lib/module/$MAJOR_VERSION ?

i've double checked all linux related receipts and it's clearly a choiche, i can imagine that this save space but doesn't it risk to arise problems? is it a new feature allowed by 3.X kernels? i would be glad to be pointed to a doc.

Oh right, they integrated xz in the newer version of Busybox. Maybe just use the real tar and xz as build dependencies? Should give you what you need.
