After installing Slackware: a checklist

Should be done during installation:

• partitions
• Software series:
  • server:

min: a ap d l n

max: a ap d e f k l n t tcl x y (i.e., all except for kde xap xfce)

• desktop: server/max + xap (i.e., all except for kde xfce)

• Comment out

if has("vms")
  set nobackup          " do not keep a backup file, use versions instead
else
  set backup            " keep a backup file (restore to previous version)
  if has('persistent_undo')
    set undofile        " keep an undo file (undo changes after closing)
  endif
endif

in /usr/share/vim/vimrc and run

# rm /usr/share/vim/vimrc~ /usr/share/vim/.vimrc.un~

• Label partitions
• Remove kernel-huge and fix the symlinks in /boot
• Remove lilo
• /etc/ssh/sshd_config:

Port 26
AddressFamily inet
PermitRootLogin yes
PrintMotd no
PrintLastLog no

• If root is the only user on the system:

• $ ssh-copy-id -i ~/.ssh/id_rsa.pub (from a remote machine)
• In /etc/ssh/sshd_config comment out PermitRootLogin yes and add

PasswordAuthentication no

• /etc/fstab
• /etc/mdadm.conf
• /etc/mkinitrd.conf
• /boot/grub/grub.cfg
• /etc/hosts
• /etc/HOSTNAME
• /etc/rc.d/rc.inet1.conf
• /etc/resolv.conf

Initial setup

• # chmod -x /etc/profile.d/bsd-games-login-fortune.sh
• Disable unneeded rc-files, e.g., # chmod -x rc.acpid rc.bluetooth rc.elogind rc.gpm-sample rc.haveged rc.wireless
• Install slackscan
• Install all patches with /root/bin/slup
• # slup bash-completion
• # cp /usr/doc/git-*/contrib/completion/git-completion.bash /etc/bash_completion.d/
• /root/.bash_completion

_mkcd()
{
    local cur prev words cword split
    _init_completion -s || return
    $split && return 0
    _filedir -d
}
complete -F _mkcd mkcd

• Upgrade kernel; /etc/rc.d/rc.modules.local, blacklist unneeded modules
• Upgrade the Intel microcode
• Remove vim andi vim-gvim
• Install neovim, my-neovim-extras, and their dependencies

• Put init.vim and ru_renard.vim to /root/.config/nvim/
• mkdir -p ~/.local/share/nvim/backup/

• /etc/ssh/ssh_config

Host *
AddressFamily inet

• /etc/profile.d/lang.sh: comment out export LANG=en_US and add

LANG=ru_RU.UTF-8
LC_MESSAGES=en_US.UTF-8
LC_TIME=en_GB.UTF-8
LC_NUMERIC=en_US.UTF-8
LC_MONETARY=en_US.UTF-8
export LANG LC_MESSAGES LC_TIME LC_NUMERIC LC_MONETARY

Preserve "export LC_COLLATE=C"

• /etc/profile.d/man.sh

alias man='LANG=C /usr/bin/man'

Setting up the root account

• /root/.bash_profile

[[ -d /root/bin ]] && PATH="$PATH:/root/bin"

EDITOR=vi
VISUAL=$EDITOR
PAGER="view -"
MANPAGER="/bin/bash -c \"col -b | LANG=C view -c 'set filetype=man' -\""

echo -e -n "\x1b[\x36 q"

[[ -f /root/.bash_aliases ]] && source /root/.bash_aliases
[[ -f /root/.bash_functions ]] && source /root/.bash_functions

• /root/.bashrc:

source /etc/profile
source /root/.bash_profile

• /root/.bash_functions

mkcd()
{
[[ $# -eq 1 ]] && mkdir -p "$1" && cd "$1" \
    || echo "mkcd expects exactly one argument"
}

• If the machine is not always on change the root crontab to

# root crontab
# DO NOT EDIT THIS FILE MANUALLY! USE crontab -e INSTEAD
#
# If you don't want the output of a cron job mailed to you, you have to direct
# any output to /dev/null.  We'll do this here since these jobs should run
# properly on a newly installed system.  If a script fails, run-parts will
# mail a notice to root.
#
# man 1 crontab for acceptable formats:
#    <minute> <hour> <day> <month> <dow> <tags and command>
#    <@freq> <tags and command>

# SYSTEM DAILY/WEEKLY/... FOLDERS
#
@hourly   ID=sys-hourly  /usr/bin/run-parts /etc/cron.hourly 1> /dev/null
@daily    ID=sys-daily   /usr/bin/run-parts /etc/cron.daily 1> /dev/null
@weekly   ID=sys-weekly  /usr/bin/run-parts /etc/cron.weekly 1> /dev/null
@monthly  ID=sys-monthly /usr/bin/run-parts /etc/cron.monthly 1> /dev/null

• # install -m 0644 -o root -g root /usr/doc/dcron-*/extra/prune-cronstamps /etc/cron.d/

Further configuration

• /etc/rc.d/rc.local

# Ensure the existence of /var/lib/dbus/machine-id and /etc/machine-id
if [ -x /usr/bin/dbus-uuidgen -a ! -x /etc/rc.d/rc.messagebus ] ; then
  rm -f /var/lib/dbus/machine-id
  rm -f /etc/machine-id
  /usr/bin/dbus-uuidgen --ensure
  ln -s /var/lib/dbus/machine-id /etc/machine-id                                fi

• /etc/rc.d/rc.local_shutdown

#!/bin/bash
#
# /etc/rc.d/rc.local_shutdown:  Local system shutdown script.
#
# Put anything that needs to be run at shutdown time in here.

# Clean /tmp
/usr/bin/find /tmp -mindepth 1 -delete

• Set ntp servers in /etc/ntp.conf
• /etc/cron.daily/fstrim:

#!/bin/bash
/sbin/fstrim /

• # sensors-detect. Add modules for lm_sensors to /etc/rc.d/rc.modules.local

• /etc/smartd.conf. For HDD:

/dev/disk/by-id/ata-...  -a -o on -S on -I 9 -I 190 -I 194 -m root -s (S/../.././04)

For SSD, substitute "S" in parentheses with "L".

To start smartd uncomment the corresponding lines in /etc/rc.d/rc.M. If the machine is not always on, add the option --savestates=/var/tmp/smartd.

• Creat /etc/X11/xinit/xserverrc

#!/bin/bash
exec /usr/bin/X -dpi 94

• Creat /etc/sysctl.conf

# Change tcp congestion control to bbr
net.core.default_qdisc=fq
net.ipv4.tcp_congestion_control=bbr

1. Increase the maximum number of inotify watches per user

fs.inotify.max_user_watches=1048576

1. To disable mtp comment out the line

SUBSYSTEM=="usb", GOTO="libmtp_usb_rules"

in /lib/udev/rules.d/69-libmtp.rules
