Recompiled kernel and broke RPM db? How?

Pcghost · 07-10-2003, 01:14 PM

Yesterday I recompiled the kernel on my laptop with all the bells and whistles I need. And now when I boot that kernel, I get an error when installing rpm packages. It says it cant read the rpm database. How is it possible to break that by compiling the kernel? I never saw anything referring to RPM in the configs.

Just a coincidence ... RPM sucks all
by itself, no kernel involved...

That's what I thought, but why then does RPM work when I boot the older kernel? I can run apt under my old kernel but it errors when I try using the new (2.5.68) kernel.

And I know RPMs suck and all, but sometimes I just want that quick fix install (when it works).

w000t :}

I haven't tried any 2.5 series kernels, and
wouldn't know how/what in the kernel code
would change the berkley DB .... maybe some
sort of new permission/ACL thing going on?

Or the filesystem of the mountpoint where
the DB lives isn't supported in your new kernel?

Ok ok, I will tone down my ambition.

I figured if I was going to make a bad*ss custom kernel for my laptop I might as well go for broke and use a newer kernel. The strange thig is, when I tried to make xconfig the 2.4.21 kernel, alot of the features I needed were greyed out, so I couldn't select them. Things like ACPI support. I am so close to having a really hot system here, I just need to get my kernel perfect.

Just out of curiousity, when I do hit "perfect" on my new kernel, how do I backup the built kernel so I can restore it if things ever go wrong?

Thanks for the help Tink..

Ummm ... the greyed bits happen if you don't
select the "experimental" feature in the top
most menue....
As for the ACPI support: make sure you grab
the acpi patch from http://acpi.sourceforge.net
The patch against 2.4.21.rc3 also works with
the actual 2.4.21 kernel....

As for the backup ... just copy one of each
working kernel to roots home ;) (it's a good
idea to copy the corresponding .config &
System.Map files, too)

Thanks alot Tinkster. It turned out my problem was the fact that I was recompiling a developement kernel. I went back and downloaded the 2.4.21 kernel, patched it for acpi and now have a virtually perfect kernel running on my laptop. The only problem I have now is figuring out which selection in the"filesystems" section controls the iso-8859 filesystem. I get an error that says

cannot locate module nls_iso-8859

Once I correct that, I have mastered the kernel config. Woohoo! :-)
