This recipe provides a config file for core-image-minimal.
This config file is used for volatile storage handling in case of a
readonly rootfs.
Also, let core-image-minimal depend on this recipe.

I am still digging into this idea of having a image specific volatile
package, RP is not wild about it either. What's different now from
before is the minimal version cut down from the orignal version? Is
there any reason we can't use a larger volatile conf?
Sau!
Hi Saul,
I thought about this, but didn't dig deep into it because I thought one
conf file for one image would be clearer.
On a second thought, maybe we could use a config file like below.
<pkg1>
readonly specific config items for pkg1
</pkg1>
<pkg2>
readonly specific config items for pkg2
</pkg2>
....
(Let's denote it as the original config file.)
In this way, all config items are centred into one place.
And the strategy would be like:
1. get a list of pkgs that are to be installed on target
L = [pkg1, pkg2, ..., pkgn]
2. original config file -- [select items according to L] --> final
config file
The selecting procedure is simply something like:
for pkg in $pkgs; do cat origin | sed -ne "/<$pkg>/,/<\/$pkg>/ {
/<$pkg>/n; /<\/$pkg>/n; p; }" ; done > final
The final config file should look like the ones that we use for now
so that we can still use populate-volatile.sh to create the dirs and links.
3. Parse the final config file with populate-volatile.sh to create the
proper directories and links.
The problem is that I don't know how to get the pkg list.
Could somebody help me?
What do you think about this strategy?
Cheers,
Chen Qi
