clean up /boot cos it is too full

nerak99 · 02-18-2010, 10:10 AM

I have this as a ls in /boot
It (/boot partition) is getting full!
Which of these can I safely delete or move?

Fedora initramfs is really 12M? Wow!

Anyway, you'll be fine with one matching set: config initramfs System.map vmlinuz vimlinuz.xx.debug.

Assuming your running with the newest of these, 2.6.31.12, and it's working for you, it's okay to delete all the others.

You need grub/, and I'm not sure what efi/ is, so leave those be...

Type "uname -a" and find out which kernel you're currently running. Presumably that's the one you boot to all of the time.

If so you can probably "safely" remove all of the files not associated with that version. However, rather than simply remove them you should use "rpm -qa |grep <version>" to see if they were installed as part of an RPM (they likely were) then use rpm -e <package> to remove the RPMs so it will clean up the kernels directories as well.

Your list though makes it look like these might have been manual compiles for testing so you might want to find out why they're there before deleting anything.

I am a bit concerned about how all that got there in the first place....Have you been doing a lot of system upgrades? Re-compiling the kernel?

Here's my /boot (after several system upgrades):

Code:

[mherring@mystical ~]$ cd /boot
[mherring@mystical boot]$ ls -l
total 12172
drwxr-xr-x 2 root root    4096 Jan 31 13:31 grub
-rw-r--r-- 1 root root 7275869 Feb 17 10:20 kernel26-fallback.img
-rw-r--r-- 1 root root 1899872 Feb 17 10:20 kernel26.img
-rw-r--r-- 1 root root 1303637 Feb  9 14:14 System.map26
-rw-r--r-- 1 root root 1972128 Feb  9 14:14 vmlinuz26
[mherring@mystical boot]$ du -sh
13M     .

Note that "kernel26*" is Arch's name for the initrd files
