Thanks for pointing it out. The box is several years old and as you pointing it out the guidelines those days were 30MB |

That file is very small: |

34K Mar 5 11:46 /boot/grub/splash.xpm.gz |

I like your solution #4. Will it work? |
| 62 |
|
| 63 |
Current fstab: |
| 64 |
/dev/sda1 /boot ext2 noauto,noatime 1 2 |
| 65 |
/dev/sda3 / ext4 noatime 0 1 |
| 66 |
|
| 67 |
Change to: |
| 68 |
/dev/sda3 /boot ext4 noatime 0 1 |
| 69 |
/dev/sda3 / ext4 noatime 0 1 |
| 70 |
|
| 71 |
Copy from /dev/sda1 "/boot" to /dev/sda3 /boot |
| 72 |
|
| 73 |
grub.conf: |
| 74 |
kernel /boot/kernel-current root=/dev/sda3 vga=normal |
| 75 |
|
| 76 |
Since fstab is pointing to sda3 I don't think I need to change anything. |
