Hello,

hmm, ok.  But eleven lines earlier the test to set $::progs{'lzmadec'}
uses -x; thus, if the file system is mounted noexec, that hash element's
value is just 'lzmadec' (without a path), and the -r test will fail
anyway (unless there's a file called 'lzmadec' in the current directory,
which would make things certainly even more fun ;-)).  In this case
setup_programs() would return -1 but should return 0 according to the
comment above the subroutine.

(Ok, the -x test is part of a patch I once sent and which you committed,
so blame me if it's wrong ;-).)

Sure, that's what I did: I copied the TL binaries to ../bin/i386-netbsd/
and then used install-tl to install the machine independent files.

I just wondered why it shouldn't be possible to e.g. list the supported
archs (`tlmgr arch list') just because the arch I'm running tlmgr on is
not supported...

Hmm, but I think we already reached a [1]consensus on this...
