I'm starting an instance on Amazon EC2, and it does a fsck at boot and restart.
The console output at the start is:
* Checking root filesystem .../dev/sda1: Adding dirhash hint to filesystem. /dev/sda1 primary superblock features different from backup, check forced.
It does a fsck and restarts.
I'm creating my own AMI from a local loopback image. It's not based on any of the exiting Amazon AMIs. Is there something I can do to prevent this from happening? The instance comes up fine after the automatic restart, but it's a pain cause it delays when it's available.
