How can I twin booting two copies of macOS on the identical machine with Apple Silicon/APFS?

As a preface, I wish to point out that I am conscious that twin booting beta/bleeding edge variations of macOS alongside the secure public launch can yield a state of affairs the place firmware is up to date on Apple Silicon machines to match the firmware of the beta OS, which is a a method road, and may trigger points. I do not assume that applies right here as right here, I am asking about the suitable strategy to twin boot two copies of the identical public, secure, model of macOS,

i.e. two copies of 14.7 Sonoma (which I want to check software program in each manufacturing and vanilla environments) – the “base” system is the principle manufacturing OS set up, the “vanilla” system is the check second OS set up.

This is what I’ve performed:

1. Create a brand new APFS quantity group within the root:

This provides one new quantity that is ‘installable’ to, which appears to be like like this in DiskUtility:

/dev/disk3 (synthesized):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      APFS Container Scheme -                      +994.7 GB   disk3
                                 Bodily Retailer disk0s2
   1:                APFS Quantity Macintosh HD            10.3 GB    disk3s1
   2:              APFS Snapshot com.apple.os.update-... 10.3 GB    disk3s1s1
   3:                APFS Quantity Preboot                 6.1 GB     disk3s2
   4:                APFS Quantity Restoration                936.4 MB   disk3s3
   5:                APFS Quantity Information                    786.5 GB   disk3s5
   6:                APFS Quantity VM                      1.1 GB     disk3s6
   7:                APFS Quantity macOSSecondCopy         802.8 KB   disk3s7

After set up disk3s7 continues to be current and disk3s8 has macOSSecondCopy - Information.

2. I booted into the brand new macOS set up (holding energy button on the MacBook) – all the things regarded regular, did not signal into any companies/iCloud and so on, simply actually vanilla, ran some damaging checks which borked the set up, now I wish to take away.

3. Again within the base atmosphere, I merely deleted your entire macOSSecondCopy quantity group, and it appears to be utterly eliminated.

The one uncommon factor I’ve seen is that after I log into the vanilla set up every time it prompts me to unlock the bottom installs quantity and to enter my password.

Does this sound like an affordable strategy to run, check after which delete a 2nd copy of the identical model of macOS as the bottom, with out inflicting points to the Mac or my Apple ID/FindMy/Companies and so on?

If not, is there a cleaner strategy to twin boot two copies of macOS (identical model or in any other case)?
