Our mktemp(1) implementation uses 8-X for a temp file by default. That's ok, but we should increase the value from 8 to 10 as many other OS already did. PR: 261438

/*
|
|
* This program was originally written long ago, originally for a non
|
|
* BSD-like OS without mkstemp(). It's been modified over the years
|
|
* to use mkstemp() rather than the original O_CREAT|O_EXCL/fstat/lstat
|
|
* etc style hacks.
|
|
* A cleanup, misc options and mkdtemp() calls were added to try and work
|
|
* more like the OpenBSD version - which was first to publish the interface.
