: Modified files:
: sbin/sysctl sysctl.c
: Log:
: Don't write the name of the sysctl to a temporary variable and truncate
: it on the '=' there. If the argument is actually longer than the buffer,
: this would result in a NULL reference. Instead, allocate the necessary
: buffer with alloca and copy the name part.

Use malloc instead of alloca please. Also, alloca is non-portable
and using it inside a braced substatement is even more non-portable.
