After a apt-get update/apt-get upgrade ended with errors, my system became unusable. I was able to determine that the /boot partition was missing several files (useful ones, like kernel.img...)
I copied the missing files from another pi's /boot partition, but I don't know if the versions are in sync with this one. The pi does boot, and seems to work correctly, although a couple of my startup customizations seems to have been lost.
Is there a list of packages that I should reinstall to sync the files in /boot?
The only files that were on /boot after it was corrupted were:
-rwxrwxrwx 0 tom staff 152 Jan 19 2014 cmdline.txt -rwxrwxrwx 0 tom staff 1179 Aug 25 2013 config.txt -rwxrwxrwx 0 tom staff 137 Feb 9 2013 issue.txt -rwxrwxrwx 0 tom staff 3572200 Oct 28 03:09 start_x.elf
(this list is from a tarball I made on my mac before I copied files from the other system, thus the unusual owner/group)
