Using value taken from another, already installed machine, from ls /dev/disk/by-uuid is working.
I tried to search the web but I was not able to find any restriction about UUID usage.
Could someone point me some documentation about the controls done on UUID for MaaS partitioning ?
Thanks in advance,
Have a nice day,

Sure, here you can see the validation that is performed by MAAS. It’s a regex match on UUID4 format.
By heart if you remove that check and you try to use UUID1 or UUID5 it might work as I’m not aware of any restriction. But UUID4 is the standard for fs uuids.
Not specifically about MaaS, but if you have, I’ll take them.
It is just to understand if there is any restriction, for any reason, to use UUID1,2,3,4,5 for partition UUID, explained somewhere, as I did not have a good understanding about UUIDs.
Thanks for your answer.
I quickly go trough your link and I guess that I did know and understand all that.
The question is more about UUID version X VS UUID version Y and why it is limited in MaaS.
Which may be linked in how they are used by the underlay linux.
