Void changes kernel parameters |
|
In February the Void team reported they would be switching from the LibreSSL cryptography library to OpenSSL, which is more commonly used among Linux distributions. Following this news, the Void project undertook a massive rebuild of packages which rely on OpenSSL and also made some adjustments to kernel hardening. The new kernel changes can cause older computers to run more slowly and suffer from longer boot times. "As a consequence of these changes, Void's default kernel command-line now omits the slub_debug and page_poison options. There is a chance that your existing system still has the old options enabled. They still work in newer kernels, but have a performance impact more in line with init_on_free=1. On older hardware this can be quite noticeable. If you are running a kernel series older than 5.4, you can keep them (or add them) for extra security at the cost of performance; otherwise, you should remove them." Details on both changes can be found in the Void project's news post.
