Unfortunately, there's not a simple answer to this. The Linux kernel can be compiled to support any number of CPUs. According to some distribution-specific support documents I found in researching this answer, the number ranges from 1-4, 64, 1024, and 'unlimited' in the case of Red Hat Enterprise Linux.

When the Kernel is compiled, there is a configuration directive passed to the compiler ('NR_CPUS') that determines the maximum number of CPUs supported.

My suggestion is to research your specific distribution and see what the developers compiled the kernel to support. It should be readily available on their documentation (I was able to find this easily for many common distributions).

How does PC-BSD measure up for a desktop computer OS?

How many hard drives can Linux handle?

How many can you put in your computer? Linux can support massive servers with hundreds of hard drives. I believe the mainline kernel supports up to 702 hard drives, although patches are available for up to 3904 disks. You're far more likely to run into hardware limitations than you will with how Linux handles hard drives.

Is SELinux preinstalled in Arch Linux?

No. Its support status in Arch Linux is currently unofficial with the official Arch kernel. However, if you want SELinux, there is a hardened version of the kernel you can install, along with a few rebuilds of core packages with SELinux support from the AUR. The information on what packages need to be rebuilt can be looked up in the SELinux article in the ArchWiki.

How long can the path file length from home in Linux be?

Starting from /home, the path may include up to 4,091 additional characters (that is, Linux supports 4096 characters for the path, with up to 256 characters per file or directory name). This is a limitation of the kernel, and not of the file system. It is technically possible to modify the Linux kernel to support even longer file and path names if a user needed to do so.
