/ is full, can't installkernel

[thevirtuesofxen]

I ran installkernel and it stopped saying the filesystem is full. I can't reboot until this is done, so any help is greatly appreciated. The HD is 30 GB, and here is the output of df and ls -la /boot

Is there anything I can clean out of there?

How is it that your root partition is full? I still have 375MB free on mine, which is 512MB.

You said that you can't boot without this completing, which implies that something is wrong with your current kernel. If you don't need it, then copy it to another location, possibly your home directory, and delete the original instance from /boot. This will free up enough space for you to install the new kernel, or at least it should.

[thevirtuesofxen]

I did something stupid. I moved kernel.old to /root, which was on the same slice. I need some sleep.

[pickupsticks]

I would go through and delete all the kernel modules that you will not need. There is sure to be tons of them and they take up substantial space.
I found this same problem recently, I kept the same space I had before in / for 6.X and installed 7. I then ran out of space after building a new kernel also.

Please use du to find what is tying up your space. 512 should be enough. You may have some dump files hanging around in /, or maybe /var or /tmp is on your root partition (which is wrong.)

# du -hHxd1
Check man du(1) for the meanings of those options.
