Grub2 can load the image from /usr/share/rescue-image/rescue.img if you
don't have that encrypted. Space in /boot is indeed precious if you made
that a seperate partitions years ago. Just for comparison:
Kernel without module and a kernel independent initramfs with some
rescue tools included:
-rw-r--r-- 1 root root 4.5M May 14 2011 vmlinuz-2.6.39-rc7-xen-1
-rw-r--r-- 1 root root 3.0M Feb 21 2010 initramfs.2010.02.18
With my own kernel I use up 4.5MB per kernel version I keep around plus
one initramfs for all versions. Or 9-10 kernels for your 50MB /boot.
Debian kernel and initramfs:
-rw-r--r-- 1 root root 2.6M Nov 14 09:21 vmlinuz-3.1.0-1-amd64
-rw-r--r-- 1 root root 11M Nov 29 18:01 initrd.img-3.1.0-1-amd64
With Debians kernel it's down to 4 and no rescue tools included.
