[meta-arago][master/scarthgap][PATCH] meta-arago-distro: recipes-core: Add no-fstab-update option to WIC_CREATE_EXTRA_ARG

[Chirag Shilwant]

- Ideally running `ls /boot/` in filesystem should list contents from /rootfs/boot partition
but currently it lists the contents of /boot partition of the WIC Image.

Eg - Incase of AM64x,
```
    root@am64xx-evm:~# ls /boot/
    EFI  Image  tiboot3-am64x-gp-evm.bin  tiboot3-am64x_sr2-hs-evm.bin  tiboot3-am64x_sr2-hs-fs-evm.bin  tiboot3.bin  tispl.bin  u-boot.img  uEnv.txt

```

- To fix this issue, add --no-fstab-update flag to WIC_CREATE_EXTRA_ARG in arago-image.inc
to prevent WIC image from adding an additional entry in /etc/fstab.

Will this change affect EFI? As there's EFI directory in that partition.

This flag is global and will prevent all other partitions from populating 
/etc/fstab properly. Sure, meta-ti only has /boot and / defined, but other 
layers could have own wic files with e.g. /home or /data partitions. Mounting 
those will require a custom /etc/fstab instead of wic creating corresponding 
entries automatically.

The EFI partition under /rootfs/boot will still be present.
Following is the output of `ls /boot` with this patch,

```
root@am64xx-evm:~# ls /boot
EFI  Image  Image-6.1.80-ti-g2e423244f8c0 dtb  fitImage  
fitImage-6.1.80-ti-g2e423244f8c0

Apparently, this change was being carried in processor sdk layer from
quite a long time (from dunfell) to resolve a customer issue reported by 
Andreas.
Diving into our internal JIRA system showed that this fix was suggested 
by Andreas
& was resolved by the SDK team back then by keeping this change in 
processor sdk layer [1].
Not sure why this was in processor sdk layer though. Maybe Andreas can 
provide additional details.

Btw, I also see other SOC vendors (meta-freescale) adding 
--no-fstab-update flag to WIC_CREATE_EXTRA_ARG [2]
So, if we are planning to pull in this change should it go somewhere in 
meta-ti (maybe k3.inc [3])?

Fyi, This is not a k3 only issue. We fix this for pretty much all ti
products.  We've fixed this for years on our own layer by defining our own
wic image which removes the /boot.

Setting --no-fstab-update wouldn't break our solution, though i do wonder
if it's too heavy handed.

https://support.criticallink.com/gitweb/?p=meta-mitysom.git;a=blob;f=wic/sdimage-bootpart-nomountboot.wks;h=1e2c3927de62cd33382733fd4fdd24047a7d8fd9;hb=refs/heads/kirkstone

Ps. Not sure if anyone from meta-edgeai is on here but why would you rename
the boot partition to BOOT and change the rootfs name... Anyways I digress.

Thanks, I'll do some additional testing with EFI a bit later.

I tested and submitted a different fix last night to adjust WIC templates to 
not mount boot partition under /boot directory[1]. I still believe doing it 
just for that one partition is better than disabling fstab updates globally.

Can you please take a look and maybe test this option for your use case?

Looks good to me.

Though i'm curious what the /boot -> boot part does. When we did it we
deleted the /boot entirely.

Also while we are touching the file. Could add the M to "128" in the non
efi file so it matches and is more clear.

So with the above referenced patch in meta-ti, I'm assuming we do not 
need this patch in meta-arago?

wic --help says:

    * 'part' or 'partition'

       This command creates a partition on the system and uses the
       following syntax:

         part [<mountpoint>]

       The <mountpoint> is where the partition will be mounted and
       must take of one of the following forms:

         /<path>: For example: /, /usr, or /home

         swap: The partition will be used as swap space.

       If a <mountpoint> is not specified the partition will be created
       but will not be mounted.

       Partitions with a <mountpoint> specified will be automatically mounted.

So, the <mountpoint> part is optional, you can definitely fully omit it. But, 
I've seen many layers use it as a name, mostly in cases of --source=rawcopy 
or --source=empty as those don't have a --label parameter. But it behaves the 
same with --source=bootimg-partition and won't treat it as actual mountpoint 
when it doesn't start with a / character. It's rather undocumented, but it 
works. I guess we can also remove it to just follow the docs, since we have 
label as well to avoid confusion...

I guess I can send a v2 for that...

That's my pitch here.

Chirag,

Will that work for you and others?

Let me kickoff a build with your meta-ti patch [1] & see if that works 
for us as well.
Will get back in a day or two.

Ryan, We can ignore this patch.
Since we have integrated Denys patch in meta-ti, I will go ahead
and remove WIC_CREATE_EXTRA_ARG from meta-tisdk as well [1]

Denys,

As you pitched, it works for us as well.
I don't see the boot binaries under /rootfs/boot with your meta-ti patch [1]
Running `ls /boot/` in filesystem now lists the following,

```

root@am64xx-evm:~# ls /boot/
EFI  Image  Image-6.1.80-ti-g2e423244f8c0 dtb  fitImage  
fitImage-6.1.80-ti-g2e423244f8c0

```
