Re: upgrading binary failed - execve - too long argument list

At-least on my system ARG_MAX depends on the size of ulimit.

# getconf ARG_MAX
2097152
# ulimit -s unlimited
# getconf ARG_MAX
4611686018427387903

Meaning no kernel recompilation should be necessary to adjust the maximum
argument space.
