I've been using busybox mdev instead of udev in many projects, which so
far has worked excellently.
Each of these projects needed similar patches to busybox to make it work,
so I think its time these changes move into the core for everyone to use.
This first series fixes the touchscreen support. A patch to automatically
have mdev mount storage devices will follow soon, I'm still testing it.

mdev.conf references the find-touchscreen.sh script, but this file
was not being installed. Add the script to the busybox-mdev package.

Simplify the grep expression, use the more common "grep" command instead
of "egrep", avoid forking extra processes, join multiple invokations into
a single combined expression.
Change the touchscreen regex so that it also recognizes various USB
touchscreen controllers and the ad7879 i2c device.
Based on code used in OpenPLi and meta-topic.

I enjoy this idea but please put this one in a specific sub-package or
with a setting in /etc/default/mdev to enable/disable it.

By "this" you refer to the automatic mounting? No problem, and a good
suggestion too.
Another problem I solved in various projects is the automatic loading of
kernel drivers. It makes mdev automatically load modules and firmware, e.g.
when plugging in a USB device, and adds a script to scan for hotpluggable
devices at boot. It's only a few lines, but these make mdeve provide most of
udev's functionality.

Upon inserting a USB stick or similar device, mdev will run
an automounter script that mounts valid partitions on
/media/<device>. The script first checks /etc/fstab entries
so that mounting on UUID or LABEL or using custom mount options
is still possible. If /etc/fstab does not contain particular
mount options, the script will create (and remove) the mountpoint
automatically.
The script also supports full disk partitions (devices without
partition table).
The automatic mounting can be disabled by adding a line
MDEV_AUTOMOUNT=y
into /etc/default/mdev
Automatic mounting for a particular device can be disabled by
creating a file "/dev/<device>.nomount". This is helpful in
scripts that create partitions for example, and want to perform
specific actions which require the device to remain unmounted.
A more complex variation (using LABEL based mounts) on this script
has been in use in OpenPLi for many years now, and I've used this
one on many projects already, so it's about time to push this to
mainline.

Add a line to mdev.conf that tells mdev to load kernel modules when
required.
For example, if you built wifi support as an external module, inserting
a wifi stick into a USB port will now automatically load that module
into the kernel and the wlan device will be ready for configuration.
Without this patch, you have to load required modules manually or force
them to load at system startup.

Agreed and I think this is also a good addition; however we should
have it in a subpackage as well.

"busybox-mdev" is already a separate package. Both automounter and module
loader need an entry in mdev.conf to work. (The module loader is nothing but
an entry).
If projects or users don't want these, they can provide their own mdev.conf
(it's a CONFFILE anyway). This just makes for a better default.
The "load modules at boot" script is yet on its way, it contains about 3 lines
of shell script which only make sense for mdev, so putting that in a separate
package seems overkill to me.
(PS:)
From the current state of busybox-mdev in OE-core, my perception is that
there are only a handful of projects in the world that use it, and I'm a
member of two of those...

Thanks for this, but can this script be put into a separate recipe to make
it even easier for people who don't want it, or want their own version?
The prior art here is the udev automounting script which is in
udev-extraconf.

That embarrassing moment when you realise that Otavio said the same thing

Also it would be nice if the path matched the most recent
use in udev which is /run/media/<device>

Putting the script into its own package is no problem, but how does one
arrange this with mdev.conf?
For the automounter to work, mdev.conf needs extra entries to call the script
when block devices appear/disappear.
Unlike udev, mdev only has one config file.

Of course, these locations need to move around every few years, otherwise
people would be expecting things to remain in place...
I'd rather keep using the /media symlink, as it gives distributions a chance
to move things around.
On the satellite settop boxes, /media is a 64k tmpfs mount. This is because
when a mount fails, the box may end up writing a TV recording to wherever
/media happens to be. It that's flash or a big tmpfs, the box will commit
suicide in mere seconds by either filling the flash or eating up the precious
RAM. And for some things, the box really needs a big tmpfs, so just reducing
the volatiles' sizes wasn't an option.
Having said that, if this is blocking, I'll do a s./media./run/media.g on the
file, getting this mainlined has higher priority.
M.

I didn't try but what happens in mdev if the script does not exists? I
mean keep mdev.conf as is (ready for use) and move the script to
another package which can be installed or not.

Nice 'solution' to avoid a more serious problem :-D

I prefer to have it behaving as udev as much as possible, by default.
However, the script could source a defaults file (if it exists) to
change the mounting point for example and allow for those special
systems to be handle without forking.

That's a fairly good argument for keeping it in the same package, and we
can expect that users of mdev will be providing their own configuration
file anyway.

Indeed. I was just implementing the split up, but it looks weird. You end up
with a package "busybox-mdev" that contains nothing but an initscript and a
config file (because the actual "mdev" binary is supplied by busybox), which
refers to scripts that don't exist, and then an extra busybox-mdev-extraconf
that supplies these scripts, but doesn't actually contain any configuration
files in spite of its name. And then I had to find a way to get this package
installed by default, which also isn't trivial.
So can we keep it al in busybox-mdev? It's a tiny config package anyway, and
when providing private configs (which should rarely be needed now), it's easy
enough to replace these in a bbappend.

I've been using busybox mdev instead of udev in many projects, which so
far has worked excellently.
Each of these projects needed similar patches to busybox to make it work,
so I think its time these changes move into the core for everyone to use.
v2: I joined the two patch sets together.
The first two fix the touchscreen support.
The third makes the system automatically load kernel modules when
you plug in a device.
The fourth adds automounter capabilities. In v2 the default location is
/run/media, which can be changed in /etc/default/mdev.

mdev.conf references the find-touchscreen.sh script, but this file
was not being installed. Add the script to the busybox-mdev package.

Simplify the grep expression, use the more common "grep" command instead
of "egrep", avoid forking extra processes, join multiple invokations into
a single combined expression.
Change the touchscreen regex so that it also recognizes various USB
touchscreen controllers and the ad7879 i2c device.
Based on code used in OpenPLi and meta-topic.

Upon inserting a USB stick or similar device, mdev will run
an automounter script that mounts valid partitions on
/media/<device>. The script first checks /etc/fstab entries
so that mounting on UUID or LABEL or using custom mount options
is still possible. If /etc/fstab does not contain particular
mount options, the script will create (and remove) the mountpoint
automatically.
The script also supports full disk partitions (devices without
partition table).
The following environments can be set in /etc/default/mdev:
MDEV_AUTOMOUNT=n (Disables automounting completely)
MDEV_AUTOMOUNT_ROOT=/media (Change the mount root location)
Automatic mounting for a particular device can be disabled by
creating a file "/dev/<device>.nomount". This is helpful in
scripts that create partitions for example, and want to perform
specific actions which require the device to remain unmounted.
A more complex variation (using LABEL based mounts) on this script
has been in use in OpenPLi for many years now, and I've used this
one on many projects already, so it's about time to push this to
mainline.

Add a line to mdev.conf that tells mdev to load kernel modules when
required.
For example, if you built wifi support as an external module, inserting
a wifi stick into a USB port will now automatically load that module
into the kernel and the wlan device will be ready for configuration.
Without this patch, you have to load required modules manually or force
them to load at system startup.

I just tried, removed the script and inserted a stick. It still created
/dev/sda and /dev/sda1 so it seems nothing really bad will happen then.

Well, it got rid of tons of "check if this and that" code in the recorder code
which occasionally would still be fooled into recording onto flash or RAM.

Yeah, something like "MDEV_AUTOMOUNT_ROOT=/media" in /etc/default/mdev should
do the trick.
