#define MAXINTERP 64 /* max interpreter file name length */
The above is in <sys/param.h>. It makes many modern scripts for
commercial packages (typically for binary emulation), which want
to do things like
#!/path/to/customized/perl/interpreter -I/path/to/custom/libs -I/path/to/more/libs
bomb. This number really needs to be kicked up to at least 100 or so.
Or, better yet, kern_subr.c could check that the *interpreter path* is
the length actually checked, and leave its arguments out of the length
check. Even so, interpreter pathnames may still be longer than 64....
grep MAXINTERP /usr/include/sys/param.h
Increase the number for MAXINTERP.
