[SOLVED] /boot full after grub2 installation

Hi guys !

I decided to upgrade my old grub-legacy to grub2.
I followed the wiki page, everything is working well.
There is only one annoyance: after login, I get a notification telling me that /boot is almost full.
I installed arch months (years ?) ago and I choose default size for /boot, which happens to be 32M.

$ df -h | grep /boot
/dev/sda1        31M   28M  1.1M  97% /boot

$ ls -alh /boot
total 19M
drwxr-xr-x  4 root root 1.0K Jul 24 21:58 .
drwxr-xr-x 20 root root 4.0K Jul 24 22:14 ..
drwxr-xr-x  6 root root 1.0K Jul 24 22:33 grub
-rw-r--r--  1 root root  13M Jul 24 21:52 initramfs-linux-fallback.img
-rw-r--r--  1 root root 3.3M Jul 24 21:52 initramfs-linux.img
drwx------  2 root root  12K Apr 13 12:06 lost+found
-rw-r--r--  1 root root 3.3M Jul 20 08:27 vmlinuz-linux

# du -h /boot/
2.5M	/boot/grub/fonts
2.7M	/boot/grub/themes/starfield
2.7M	/boot/grub/themes
1.8M	/boot/grub/i386-pc
2.5M	/boot/grub/locale
9.4M	/boot/grub
12K	/boot/lost+found
28M	/boot/

/boot/grub weighs about 10M while grub legacy was about 500K !

Is there any solution to lighten /boot ? I see a couple of these:

• removing /boot/grub/themes: I don't care about themes

• reinstalling grub-legacy

I'm also surprised that initramfs-linux-fallback.img weighs 13M.

Or isn't this poor remaining size a problem ?

Thank you for helping,
Yimgo

(Please excuse my shaky English)

Re: [SOLVED] /boot full after grub2 installation

Regarding the fallback image, do you have any unnecessary hooks in mkinitcpio.conf?  And have you tried different compression methods?

EDIT:

MODULES="i915"
HOOKS="base udev autodetect pata scsi sata filesystems usbinput fsck"

When setting COMPRESSION to gzip, image files weigh exactly the same.

If you don't use the starfield theme you can remove it. You can also remove unused locales I think.

Re: [SOLVED] /boot full after grub2 installation

gzip compression is done by default if you don't set COMPRESSION.

Also, look into removing one or more of pata, scsi, and sata from HOOKS.  You really shouldn't need all three.

Re: [SOLVED] /boot full after grub2 installation

Did you consider using syslinux instead ?
it is much lighter then grub2 is and easy to install

Re: [SOLVED] /boot full after grub2 installation

Compressing using xz for example the kernel?
big the /boot by about 10M (shink Swap if possible to reach the 10M)
