Questions about vold.conf and vold.fstab.

[Diego Rondini]

Hi everybody,

I'd like to ask some questions about vold, because I could not find any
valuable "official" documentation about it. I know that the sources are in
/system/core/vold/ but having some hints (or pointers to where to look at)
would be nice. So thanks in advance.

What's the difference between vold.conf and vold.fstab? I mean the rationale
betweend the two, e.g.:
- vold.conf was supported from 1.5 to 1.6 but not it's deprecated because it
cannot mount multiple partitions;
- they are both supported from 1.5 but they are used for different use cases
(e.g. vold.fstab to mount multiple partitions...).

So, although all my google searches, it's still not clear to me what vold.conf
and vold.fstab can and cannot do, from what versions they are supported (I
found this vold.fstab that refers to a 2.0 vold version:
http://pastebin.com/kfekvKbt ), and what's the reccomended way to mount
automatically devices / partitions.

Thank you,
regards,
Diego

vold.conf is the config file for old vold,
shipped since 1.5(?) to 2.1.
The source code is located in system/core/vold.

vold.fstab is the config for new vold (aka vold2),
shipped in 2.2.
The source code is located in system/vold.
(system/core/vold is removed in froyo tree).
The format of vold.fstab is easy to be understood,
and explained in the example vold.fstab
(system/core/rootdir/etc/vold.fstab)

Ok, so the "Android Volume Daemon version 2.0" I get on Android 1.6
actually means "vold1 version 2.0"; while on Android 2.2 there's
"vold2 version whatever", right?

Ok, vold.fstab is clear to me. I don't understand if using vold1 (with
corresponding configuration file vold.conf) allows to automatically
mount multiple partitions on the same device.

Is vold.conf required in froyo? Can it be discarded?

I guess that vold.conf doesn't work any more starting from Froyo
according to what Chih-Wei wrote.
