I have observed a similar behaviour under these conditions, although I could
not really explain it. I suspect it is due to a misinterpretation of other
system's grub.cfg file when generating grub.cfg.
Do you mean that something like this happens :
Say you have 3 systems: A, B, and C
Run update-grub on A and it finds A, B, and C - so 3 entries
Run it then on B and it find the 3 entries in A's grub.cfg and builds it's own
containing B, A, C (found directly) plus A, B, C copied from A's grub.cfg.
Run it on C and you get C, A, B (found directly) plus A, B, C copied from A's
grub.cfg plus B, A, C, A, B, C copied from B's grub.cfg.
Thus you quickly end up with C, A, B, A, B, C, B, A, C, A, B, C - that's 12
entries after just once round the OSs. This will quickly run out of control,
growing at an ever faster rate.
Yes, I suspect something like this. But I don't know how and why it
happens or not. It does not happen on my laptop with three successive
versions of Debian. Actually I have only seen it indirectly from other
peoples' grub.cfg.
If that's what is happening, then that suggests a lack of (effective) duplicate
detection in update-grub - or perhaps there's none at all on the basis that you
should not be having multiple installs like that ?
Err, what then would be the point in having grub-mkconfig detect and
include other Linux systems in the menu ?
