[gentoo-dev] issues with installing a new kernel

[Pete Gavin]

Hi,

I found a couple of issues with installing a new kernel...

First of all, I accidently installed the package w/o first mounting
/boot. So, after I rebooted, grub loaded the old kernel, since it
wasn't overwritten by the new one. I don't know if it would be a good
idea to mount /boot from the ebuild script, but we should maybe add
some kind of warning to it to at least remind people of it. Second, I
*do* think it would be a good idea to add depmod -a {kernel_version}
to the ebuild script, since this only changes stuff in the new module
directory, which just got installed anyways. What do you guys think?

I think it would be good if the /boot mounted check were done in the
pkg_preinst() function, which gets called right before a merge.

Yes, it's fine to call depmod -a; if possible, find a way to make it
work with ${ROOT} so that we can merge to non-root filesystems and
have depmod operate on the correct set of modules.

Thanks again,

But a /boot partition is not neccesary.

Well, I added a simple check in pkg_preinst in
linux-2.4.0.11-r3.ebuild to see if /boot exists in /etc/fstab, and if
so, it mounts it, then it will unmount it in pkg_postinst.

I also added a call to depmod -a with the -b swtich which allows you
to specifiy a root directory to use.

Well, I don't like it if an ebuild script touches my filesystem.

I use automount here for boot and /boot is a symlink to /misc/boot.

So this solution does not work for me.

Since ebuild can run in runlevels other than 1 and linux is a multiuser
operating system
such things can messup other users work.

So such a thing should only run if we are in runlevel 1

Are you shure that works. I tested such a thing a while ago and it wrote
the mdoules.conf stuff for {version} to
/lib/modules{running version}.

The problem is the mount script in /tec/rc.d/init.d. I will modify it this
week because we want to enhance
the automatic generation of /etc/module.conf.
I will take care that depmod -a really runs when neccessary.

You have a point... I didn't think it was a good idea to do this,
since everyone's filesystem setup is pretty much different... I'll
just add a message to it reminding the user to mount /boot.
