[NTLUG:Discuss] squashfs protlem editing and updating the sfs file

[Bobby Wrenn]

I have searched all the squashfs and Puppy Linux sites and can't find 
any mention of this problem. Many mention unsquashing editing and 
recreating the squashfs file. So I expect it should work, I must be 
missing a parameter.
Using Puppy Linux 4.2.0 I need to edit shell scripts in the squashfs 
file pup_420.sfs. I can unsquash the fs but when I mksquashfs the 
resulting file causes a kernel panic during boot. This happens even if I 
make no changes, just unsquash and recreate the sfs file.

I suspect the unsquash or the mksquashfs is affecting file permissions 
but I don't know where or how to prevent it.

I created the original system a few years ago as a "factory restore" 
solution for a netbook being distributed into remote areas where support 
was impossible and users have little knowledge of computers. This worked 
fine until now. The model of netbook is changing and I need to update 
some scripts. I had help when I created the original system but that 
help is not available to make a new image from scratch. I would like to 
just edit the files and distribute the new image without figuring out 
everything the other person did and recreating the whole system.

The recovery system is invoked by booting from the internal SD reader. 
Puppy resides on an 8GB SD card which is never removed and is only used 
when the factory restore is required.

Thanks,
