Kernel

I boot vmlinuz-huge, but I have generic too.

My question are can I remove everything except *huge files?

slackware 14.2

Why? They don't take up much space.

Just use the command in root 'removepkg kernel-generic'

Just a precision in case of your boot is on vmlinuz,

/boot/vmlinuz is symbolic link, if is linked on kernel-generic-4.4.14

to correct that, you have to recreate your symbolic link on kernel-huge-4.4.14

By default, vmlinuz is a link to the huge kernel, not the generic.

It can happen if you have installed or updated generic after .
but you have right in general, i have modified my post for more for precision thanks

It depends.

By default /boot/vmlinuz is a symlink to kernel image from last installed kernel package (instal/doinst.sh makes this symlink).
Packages install or upgrade are in alphabetical order, kernel-huge goes after kernel-generic if both are installed.
But if you upgrade only kernel-generic /boot/vmlinuz will be generic.
Or if you rerun doinst.sh from kernel-generic package, for ex. with

Code:

# ( cd / ; var/log/scripts/kernel-generic-* )

Since 14.2 there are new symlinks /boot/vmlinuz-generic and /boot/vmlinuz-huge (and with -smp on 32 bit). They significantly helps to configure boot loader, for ex.

Code:

image = /boot/vmlinuz-generic    # vmlinuz-generic-smp for 32 bit smp
  initrd = /boot/initrd.gz
  root = /dev/sda2
  label = Linux
  read-only
image = /boot/vmlinuz-huge    # vmlinuz-huge-smp for 32 bit smp
  root = /dev/sda2
  label = Rescue
  read-only

By "by default" I meant after installation.

Code:

lrwxrwxrwx  1 root root      19 Oct 11 00:09 vmlinuz -> vmlinuz-huge-4.4.88

I always leave that link as it is, after creating an initrd to use with the generic kernel.
Relevant bits of my /etc/lilo.conf:

Code:

# Linux bootable partition config begins
image = /boot/vmlinuz-generic-4.4.88
  initrd = /boot/initrd.gz
  root = /dev/sda1
  label = Linux_G
  read-only
# Linux bootable partition config ends
# Linux bootable partition config begins
image = /boot/vmlinuz
  root = /dev/sda1
  label = Linux_H
  read-only
# Linux bootable partition config ends

@brianL
as for me, vmlinuz-huge looks more safe than vmlunuz, say after reinstall kernel-generic package or upgrade only kernel-generic package.
