Dear Maintainer,

I intend to upload newly released lua-posix 38, which removes some
functions and breaks backward compatibility (see [1] for the full list).

lmod uses some of deprecated and noe removed functions, so I expect
it will break when lua-posix 38 will be introduced to Debian.

I guess, you'd have to patch lmod to use the new interface.
Unfortunately, simpy replacing the old name by the new one doesn't work.
For example, posix.uname is replaced by posix.sys.utsname.uname, but
the latter does not take arguments and returns a table with the results
instead of an individual field.

Here is the list of found old functions:
