well, there is no alias on the filesystem level, but only on the logical
since with PdX you do not load the (entire) ext13 library, but rather
element-by-element, logical aliases (as defined withing the object)
don't work if they don't have a corresponding filesystem alias.

a filesystem alias can be as simple as a symlink from
kalashnikov.pd_linux to uzi.pd_linux
(but then again, it might still not work, as the kalashnikoc.pd_linux
binary probably misses a setup-function for the "uzi" -name)

that's very expected behaviour: after all you do have a file
ext13/kalashnikov.pd_linux but no ext13/uzi.pd_linux.

add "ext13/kalashnikov" to the libraries to be loaded at startup?
or make an abstraction uzi.pd in ext13/, that contains a [kalashnikov]
objects and the proper iolets?

i have missed that discussion, but cyclone's uppercasing is a *design
choice* to make sure that the max compat layer does not conflict with Pd.

i'm not entirely sure why you are pushing to make Pd a "free replacement
for max/msp". both are similar and share enough concepts to make
compat-layers like cyclone feasible, but they are also different

i'd probably recomment to delete all *but* the abstraction
implementation of [uzi], as it is the only version that is guaranteed to
be 100% portable to any OS Pd will ever appear on.
