Excerpt: The Linux vanilla kernel repositories for Fedora offer RPM packages containing vanilla builds of different Linux kernel version lines. These packages are meant for Fedora users that want to access the latest Linux kernels quickly and comfortably; either the latest mainline kernel, the latest stable kernel or a vanilla variant of the Linux kernel version line Fedora uses currently.

From zram documentation: The zram module creates RAM based block devices named /dev/zramID (ID = 0, 1, …). Pages written to these disks are compressed and stored in memory itself. These disks allow very fast I/O and compression provides good amounts of memory savings. Some of the usecases include /tmp storage, use as swap disks, various caches under /var and maybe many more :)

Example of compressed swap in memory

Write this commands in /etc/rc.local to create a 2G compressed swap partition in memory.

Removes all but current kernel and headers. This is a note for personal use. Use at your own risk :)
