Somehow a particular problem with a particular application
has degenerated into a rather unfair generalization of the
whole system:
Reading about Plan 9, I was quite excited to install it. I was quite
excited when I first booted and ran it, too. But I distinctly felt my
heart sink a little
lotte% 9fs sources
lotte% diff /sys/src/cmd/rc/plan9.c /n/sources/plan9/sys/src/cmd/rc/plan9.c

char *s;
468,474c467
s = dir[f].dbuf[dir[f].i].name;
if(strlen(s) = NDIR){
pfmt(err, rc: file name too long: %s\n, s);
return 0;
}
Some, yes. But most not. At least not yet. :) I expect I might run
into trouble figuring out how to pass around strings containing NUL
bytes, though.
why would you do that? what's the application? if you tell me
