I've heard of the /boot folder, where the kernel files are situated - Vmlinuz, strange name I expected it to be Linux something, since Linux is the name of the Kernel. However, Vmlinuz is not the only crucial file to boot the system, but there are so many, that I do not know which are essential and which just expendable.
abi-4.8.0-36-lowlatency memtest86+.bin abi-4.8.0-49-lowlatency memtest86+.elf abi-4.8.0-52-lowlatency memtest86+_multiboot.bin config-4.8.0-36-lowlatency System.map-4.8.0-36-lowlatency config-4.8.0-49-lowlatency System.map-4.8.0-49-lowlatency config-4.8.0-52-lowlatency System.map-4.8.0-52-lowlatency grub vmlinuz-4.8.0-36-lowlatency initrd.img-4.8.0-36-lowlatency vmlinuz-4.8.0-49-lowlatency initrd.img-4.8.0-49-lowlatency vmlinuz-4.8.0-52-lowlatency initrd.img-4.8.0-52-lowlatency
I do not understand why there are so many files and why there are three files which starts with vmlinuz, I have not downloaded anything into the /boot folder.
uname -r shows
Does this mean I can delete all files which do not contain this release number?
