These are some scripts I wrote to make it easier to work on specific files within an initrd.gz. I publish them here just in case they are useful to others.

initrd-extract.sh: extract a file from an initrd.gz, used by the following 2 scripts
extract-bootconfig: extract "BOOTCONFIG" from an initrd.gz
extract-init: extract "init" from and initrd.gz

initrd-replace.sh: replace a file in an initrd.gz, used by the following 2 scripts
store-bootconfig: replace "BOOTCONFIG" in an initrd.gz
store-init: replace "init" in an initrd.gz

Hope it is okay to ask you to give some example what one can do with it.

Can I take out SeaMonkey and replace it with Firefox or what kind of changes does it allow?

These scripts are only useful for people modifying files that are contained within the file "initrd.gz".
No, the scripts cannot be used to add or remove applications.
I use them when modifying the "init" script that loads the various sfs files that are puppy. It means I can easily inject a different version of the "init" script into an "initrd.gz" file. This is the script that gets modified to add or remove support for boot parameters, or add support for ext3/ext4 pupsave files.

NOTE: To get some help on the parameters required by the scripts, just enter the name of the script file without any parameters.

Thanks. What about having these scripts in the "devx" SFS?

Added support for DISTRO_SPECS. and updated initrd-replace.sh so that the "bak" file is ".bak.gz" not ".gz.bak"

extract-distro-specs:
extract "DISTRO_SPECS" from an initrd.gz

store-distro-specs:
replace "DISTRO_SPECS" in an initrd.gz
