Slackware System

Useful system level notes.

Simply list files in /var/log/packages (path is actually a link to /var/lib/pkgtools/packages/).

# ls -l /var/log/packages/

List full package name (with version) only

# for that in $(ls /var/log/packages/) ; do echo $that ; done | sort

Find installed packages that are not in Slackware tree

slackfull=slackware64-15.0 ; slacktree=/home/share/slackware/$slackfull ;
for pkg in $(ls /var/log/packages/) ; do
	pkgf=$(find $slacktree/ -name "${pkg}.txz") ;
	[ -f "$pkgf" ] && continue ;
	echo "** Package '$pkg' is alien!" ;
done

This can also be done using slackview script (in my1shell repo)

# slackview find --alien

View information on specific package

# slackview find [pkg_name]

To list currently installed packages (to be used in my1live)

• get all installed packages

  # slackview file --name pkgs.txt --installed --insert

• sort based on software sets

  # slackview file --name pkgs.txt --sort

• remove those already selected for my1live

  slackview file --name pkgs.txt --dups curr.list

• rename pkgs.txt to my1live list (e.g. XXmore.list)

• run shell script (getlinux)
• select version, download source
• extract at /usr/src/ (e.g. linux-4.4.199)
• copy a config from /boot

  # cp /boot/config-generic? > .config

• use that config

  # make oldconfig

• configure build

  # make menuconfig

• build the kernel

  # make -j4 bzImage

• build/install modules

  # make -j4 modules && make modules_install

  • modules_install requires root, obviously!
• copy (as root) kernel

  cp arch/x86/boot/bzImage /boot/vmlinuz-generic-4.14.12
  cp System.map /boot/System.map-generic-4.14.12
  cp .config /boot/config-generic-4.14.12

• generate initrd if using generic

  mkinitrd -c -k 4.14.12 -f ext4 -r /dev/sda3 -m ext4 -u -o /boot/initrd.gz

  • a useful initrd generator script IS available
  • run /usr/share/mkinitrd/mkinitrd_command_generator.sh
  • then run the generated/recommended command
  • checkout the -P option if required
