Cons
Con Weak base
Sometimes updates will not execute hooks(full update always misses to run mkinitcpio) so you get an unbootable system.
Con Small development team
The team is very small
Con No real installer
Has no installer just a big bloated LiveCD that gets unpacked to your disk.
Con Pacman
Compared to deb or rpm it takes ages to update the system, it's also very dumb in dependency tracking.
Con Unreliable Servers
The CCR or the community forums are often down or unreachable.
Con Overwrites your default EFI config
It overwrites your default EFI config wich can make you PC unbootable if something goes wrong.
Con Uses systemd
Which is very hard to debug and not a *nix standard.
Con Only available for x86-based CPUs
Con Wont let you install the system to USB drives
Chakras weak installer Calamares does not allow you to install it to a USB drive.
Con Weak update process to a recent release
For example, you can install the Goedel Release and update it to the current release which then fails to boot due to some systemd-errors.
Con Installer doesn't recognise partition table SOMETIMES
On a couple of occasions the installer has told me one of my disks is missing a partition table but it definitely has one and other distros haven't presented this warning.
Con Default theming not to everyone's tastes
The default icon theme in particular is IMHO pretty ugly. Easily changed but if you like to just plug & play without changing themes it may not suit you.
