### glibc Headers Installation and Usage in Linux System Programming

For installing `glibc-headers` on different versions of Ubuntu, specific attention must be paid to the version compatibility between GCC, GLIBC, and the system core as shown by examples such as Ubuntu 16.04 with GCC 5.3.1 and GLIBC 2.23 or Ubuntu 14.04 using GCC 4.8.2 along with GLIBC 2.19[^1]. Installing these headers ensures that developers have access to necessary libraries for C programming within a Linux environment.

On Debian-based distributions like Ubuntu, one can install the GNU C Library (glibc) header files through:

sudo apt-get update
sudo apt-get install libc6-dev

This command installs not only the essential shared libraries but also includes standard libraries used during compilation processes which are part of what constitutes `glibc-headers`.

When working with custom kernels after an update, it's important to verify whether both the kernel itself alongside its corresponding development packages including headers were correctly updated since mismatches could lead to issues especially concerning drivers requiring close interaction with hardware components[^2].

In terms of modifying environmental settings related specifically to library paths for applications relying heavily upon certain versions of CUDA, adjustments might look similar to setting up additional directories under `$LD_LIBRARY_PATH`. However, this pertains more directly towards configuring environments rather than strictly dealing with `glibc-header` installations per se[^3]:

export LD_LIBRARY_PATH=/usr/local/cuda-11.0/lib${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

Regarding specialized configurations involving huge pages via hugetlbfs mounts, while relevant primarily for memory management optimizations particularly beneficial in high-performance computing scenarios, does touch indirectly on how various parts interact at lower levels influenced partly by choices made regarding compiler toolchains incorporating elements from `glibc` among others[^4].
