Improving boot time

Today, I’ve decided to try and improve the boot time of my laptop, running EndeavourOS. There was no special reason for it other than “Why not?”.

The first thing I made was disabling or masking the following systemd services:

  • systemd-resolved disabled
  • tlp disabled
  • NetworkManager-wait-online disabled
  • lvm2-monitor masked
  • org.cups.cupsd disabled
  • packagekit masked
  • bluetooth disabled (I rarely use the laptop’s bluetooth)
  • blueman-mechanism disabled

With this, I was able to save a few milliseconds and decrease the enabled systemd units to 15, but the impact was negligible.

brunomiguel@kepler: ~
└─ $: systemctl list-unit-files --state=enabled --no-pager
UNIT FILE STATE VENDOR PRESET
autovt@.service enabled disabled
avahi-daemon.service enabled disabled
dbus-org.freedesktop.Avahi.service enabled disabled
dbus-org.freedesktop.nm-dispatcher.service enabled disabled
display-manager.service enabled disabled
getty@.service enabled enabled
haveged.service enabled disabled
NetworkManager-dispatcher.service enabled disabled
NetworkManager.service enabled disabled
sddm.service enabled disabled
systemd-swap.service enabled disabled
unbound.service enabled disabled
avahi-daemon.socket enabled disabled
remote-fs.target enabled enabled
roothints.timer enabled disabled

15 unit files listed.

To further improve the boot time, I tested bfq, kyber and mq-deadline I/O schedulers. From the three, the last one allowed to shave off another few milliseconds to the boot time. Next, and last, I changed the mkinitcpio ramdisk compression to lz4 with the default compression options.

With this changes, I went from 17.040 to 15.511 seconds, decreasing a bit more than one and an half seconds in the boot time.

brunomiguel@kepler: ~
└─ $: systemd-analyze time
Startup finished in 10.145s (firmware) + 1.616s (loader) + 2.027s (kernel) + 3.250s (userspace) = 17.040s
graphical.target reached after 2.934s in userspace

brunomiguel@kepler: ~
└─ $: systemd-analyze time
Startup finished in 10.175s (firmware) + 686ms (loader) + 2.041s (kernel) + 2.608s (userspace) = 15.511s
graphical.target reached after 2.529s in userspace

In the future, I might replace GRUB2 with systemd-boot, possibly decreasing the boot time even more.

This was tested in a AMD A9-9420 CPU with the linux-zen kernel. Your mileage may vary depending on your hardware.

Updates to Jarvis, my Arch buildbot

My Arch buildbot, Jarvis, received an update today in the options logic. Now, it can receive an argument in the add (-a) and delete (-d) options, so the user can specify the package to add or delete.

The option to add a package, for now, only works for AUR. If you want to add a package that’s not in AUR, you’ll need to manually add the submodule. In the future, Jarvis will allow you to use a git repository with a PKGBUILD file.

Tony Stark would be jealous. 😉

First own package on userrepository.eu

Until now, userrepository.eu only used software from AUR. Today, to get me distracted from the flu and a respiratory infection I got a few days ago, I’ve finally created my first package for Arch Linux on my repository. It’s for a GTK web browser named Eoli and it builds from the master git branch.

Here’s the PKGBUILD at the time of writing:

# Maintainer: Bruno Miguel <omitted>
​
pkgname=eolie-git
_gitname=eolie
pkgver=da1899ff
pkgrel=1
pkgdesc="Simple GTK web browser for GNOME"
arch=('x86_64')
url="https://wiki.gnome.org/Apps/Eolie"
license=('GPL3')
depends=('gtkspell3' 'python-cairo' 'python-dateutil' 'python-gobject' 'webkit2gtk')
makedepends=('git' 'gobject-introspection' 'meson')
optdepends=('python-beautifulsoup4: Import html bookmarks'
            'python-crypto: Firefox Sync support'
            'python-fxa: Firefox Sync support'
            'python-pyopenssl: Show SSL certificates'
            'python-requests-hawk: Firefox Sync support')
source=("git+https://gitlab.gnome.org/World/eolie.git")
sha256sums=('SKIP')
​
pkgver() {
    cd "${_gitname}"
    ( set -o pipefail
        git describe --long 2>/dev/null | sed 's/\([^-]*-g\)/r\1/;s/-/./g' ||
        printf "r%s.%s" "$(git rev-list --count HEAD)" "$(git rev-parse --short HEAD)"
    )
}
​
build() {
    arch-meson "${_gitname}" build
    ninja -C build
}
​
package() {
    DESTDIR="$pkgdir" meson install -C build
}
​

Every time there’s a new commit, it will grab that source and build it. This means you might get a less than stable browser, but also that you’ll always get the latest source.

Happy free softwareing! 🙂

Metapackage for a personal installation of Arch Linux and Arch-based distributions

I’ve been using Arch or Arch-based distributions for over a year now. In this time testing a few of them, I’ve always lacked a simple and logical way of installing the same “essential” software. To tackle this, I’ve created a metapackage with all this software and this is what I’ve got so far:

# Maintainer: Bruno Miguel <https://twitter.com/brunomiguel>
