This version alows the condition you indicated (VTOC sanity=0,version=0
and no_partitions=0) to work as before as long as what were the spare1/spare2
fields in the VTOC partition entries are zero.
Can you try it out and see if it behaves correctly for fully set up VTOC
and also the previous Linux-Sun partition situation.
This should at least prevent some posible problems with posible future
versions of VTOC. It may be desirable to to reject partitions if the
VTOC is not compatible (different sanity or version > 1). What is your view?
The code will now also scan up to VTOC partitions when a validated VTOC
has been detected.
It looks like it would work and I will give it some testing,
thanks Mark.
Why don't we want to try and use 16-partition x86 Solaris labels?
Are those only found as sub-labels of MSDOS partitions?
Looking at some 2005 OpenSolaris code I have, it looks like there is a
Solaris 16 partition disk label that uses an x86 Solaris style VTOC. If I
understood the code, it is located at an offset of 512 bytes.
