[CentOS] Replacing custom kernel with another - with same identifier
Hi list, I just finished building a custom kernel from 2.6.18-53.1.21 source rpm - this time with ISA bus and ISAPNP support which I accidentally left out of my previous attempt. Unfortunately, this time I forgot to change my identifier in kernel-2.6.spec file. Thus I now have one *installed* kernel version *without* ISA support, and another one *with* ISA support but as rpm, not yet installed. Both kernels now have identical identifiers. What is the safe way to remove the previous installed kernel version without taking out the uninstalled new version? Is the latter safe in ~/rpmbuild/RPMS if I use 'rpm -e' to remove the former version? TIA Antti ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Then verify that your grub.conf/lilo.conf has the correct entry. Ah, indeed. I've never used --replacefiles in installing kernels but guess it works with them just as with any other files. Thanks!

I decided to try 'rpm -e kernelversion', 'rpm -e kernel-develversion, and then went to ~/rpmbuild/RPMS/i686 and ran 'rpm -ivh kernelversion.rpm. All went well.

I'm sure you are both right. However, I took the long path and first removed kernel and kernel-devel, then installed with 'rpm -ivh'. All went OK. Thanks anyway.

Looks like Custom Kernel HowTo survived the idiot test by me. One question though: when installing the rpms as the last step (rpm -ivh kernel-*.rpm), I get error: can't create transaction lock on /var/lib/rpm/_db.000. That means I should do it as root, doesn't it? Perhaps the HowTo could mention this even if it might be reasonably obvious that only root can install kernels...

People really in the know do not need it anyway. This raises an interesting point by itself. The role of CentOS Wiki is primarily to provide CentOS-related information or help. In the case of the kernel articles, they explain how to handle the kernel CentOS way, and many lines in there are specific for CentOS (like URLs for kernel rpms). Therefore, even Linux experts would benefit from them unless they are already familiar with CentOS, or more generally, with package-based managed systems (they tend to prefer make; make rpm, for example). Perhaps I was a bit playing the role of devil's advocate in raising the question. Of course, I'm all for HowTos in general and understand that there are OS-specific issues needing explanation no matter what level expertise one might have. On the other hand, CentOS Wiki can include more general, non-CentOS specific help as well. So, the question is what is the guidance here for writing CentOS Wiki articles with respect to CentOS relatedness. I for one don't mind at all if CentOS Wiki articles contain some general *nix advice. Most of us learn by picking up things here and there, not necessarily as a result of systematic training confined to a certain subject. The problem is finding proper balance between CentOS-related material and general *nix advice. Here newbies such as myself perhaps may contribute their little bit... I might add that I have both written and translated manuals of various electronic devices during my working career. That may explain why I am particularly interested in manuals and HowTos.

Then Alan woke up (for people who don't know he is in the UK) and made it much nicer. Akemi I just looked at the updated I Need the Kernel Source HowTo and in my eyes it is now perfect.

[CentOS-docs] Suggestions on I Need the Kernel Source Wiki pages
Hi all, I am a newcomer to CentOS but slightly less so to Linux in general (FC4-F9). In short, I am trying to make an old SB Vibra 16C (ISA) sound card work in Centos 5. To achieve this, support for ISA bus and ISA PnP is apparently needed in kernel. Therefore, a custom kernel needs to be built. -- Yes, I have read all the warnings of lack of support, etc. As a first step, I had to build the complete kernel tree according to I Need the Kernel Source CentOS Wiki. I tried to meticulously follow the directions given there but it took five or six attempts before I had a complete tree in ~/rpmbuild/BUILD/. Would you please consider the following questions in order to decide if any changes/additions are necessary in the article: a) In section 2.1 it is said: [EMAIL PROTECTED] yum install rpm-build. To 'yum install' something you need to be superuser (as confirmed by '#' prompt before the command). Shouldn't the example read: [EMAIL PROTECTED] yum install rpm-build? b) The next command on the page is rpm -i http://mirror.centos.org...;. Two of my futile attempts to install the ...src.rpm were due to the fact that 1) I did not understand and then 2) forgot to exit from root before trying to install the source rpm. Shouldn't there be at least a $ prompt (and perhaps the directory, too) before the 'rpm -i' command? c) One attempt of 'rpmbuild' failed because redhat-rpm-config is needed by kernel-2.6.18-92.1.6.el5.i686. This may not apply to everyone but it certainly applied to me who had only installed 5.1 in March and updated it to 5.2 in July by just updating when told to do so. Perhaps it would be advisable to add # yum install redhat-rpm-config to the article? d) Two attempts of 'rpmbuild' perhaps failed because I inadvertently used single quotes or apostrophes around 'uname -m' instead of `s (accent grave?). The result in prep-err.log, however, was: Building target platforms: uname -m and Building for target uname -m. I had to explicitly insert i686 in the 'rpmbuild' command like this: [EMAIL PROTECTED] SPECS]$ rpmbuild -bp --target=i686 kernel-2.6.spec 2 If this is what the user is supposed to do anyway, perhaps it could be worded a little differently to make it perfectly clear? On the other hand, if 'accent grave' characters around 'uname -m' really work in replacing the proper architecture in the command, perhaps the text should emphasize the fact? I foolishly did not cut-and-paste the 'rpmbuild' command but wrote it myself. I realize there is another thread about these Wiki pages currently being discussed on centos-docs list but I thought it better to start a new thread.
