On the contrary, the reason Linux was invented was a desire to enjoy
what Unix brings to the table, but without spending several thousand
dollars on the proprietary hardware and software to get that enjoyment,
and to have the freedom to enhance it if you choose.
Linux is very close to full POSIX compliance, prevented from being
certified as a true Unix only by a relative handful of differences whose
merit I'll leave others to argue.
Most Unix skills are directly transferable to Linux, which is useful
since Unix market share continues to decline while Linux has only grown.
But the key issue here isn't about OSes at all, but about why the
LiveCode team chose to leave both Unix and Linux support out of the
volumes function.
The answer is likely related to mount points, which these days are
equally problematic on OS X and Windows.
When originally introduced with what we now call Mac Classic, having
only the name of a mounted volume was sufficient to know how to access
it. But with OS X, is it mounted at / or /Volumes/ or somewhere else?
As noted earlier, such mount path issues are present in various forms on
all three desktop OSes.
The discussion around the enhancement request for this has been
illuminating and promising:

And JB, thanks for the catch with "Unix" - obviously that should be
"Linux", since OS X is a certified Unix and other flavors of Unix
haven't been supported by LiveCode in many years, so I submitted a bug
report to change that, pending the outcome of the enhancement request
noted above:
