I'm not sure if I understand you right, but I believe you are wondering if 
CONFIG_SYSFS is usually enabled in Linux distributions.

I think it is enabled on ALL.

Normally, it will not allow you to disable sysfs. When user manually edits 
.config file to use CONFIG_SYSFS=n, it doesn't let him - 'make' will silently 
replace it to =y automatically.

The only way to disable sysfs is when you set CONFIG_EMBEDDED=y, which is IMHO 
very rare.

I believe it is completely safe to depend on CONFIG_SYSFS.
