Package: live-initramfs
Version: 1.154.3-1     
Severity: wishlist     
Tags: patch            

To use live-initramfs for the Gibraltar firewall distribution, I ported two 
missing features from my own mkinitrd-cd package to work as scripts/hooks 
within the initramfs-tools framework and plug into live-initramfs. Although 
most can be implemented this way, a minor patch is required for the "live" 
script to:
- Call another set of scripts after finding the loopback image that is about to 
be mounted but just before actually mounting it. This allows to perform 
further checks at this stage.
- Completely bypass the unionfs mounts so that this can be handled by custom 
distribution scripts during bootup. The reason is that even larger parts of 
the filesystem should remain read-only for security reasons.

The attached patch is quite minor and non-intrusive and will not change any 
current functionality when the added options are not used. Please consider 
applying it so that the Debian package can be used without further changes.

Thanks,
Rene
