You can spell that 'use Devel::AssertOS qw(Linux)' :-)

Strictly speaking whether you have symlinks or not is a function of both
the OS and the filesystem. Linux doesn't have symlinks on, eg, FAT,
because FAT doesn't support 'em.
But if you wanted to create such an assertion, look at
Devel::AssertOS::OSFeatures::POSIXShellRedirection for something very
similar that you could base it on. You would then say something like:
use Devel::AssertOS qw(OSFeatures::SupportsSymLinks);
