Bug 515475

SUMMARY

When using the `breeze-plymouth` theme, the font in the password both doesn't work, and instead shows the white boxes/tofu symbols.

This can be fixed by forcing `/usr/lib/plymouth/label-pango.so` into the image via `BINARIES` in `/etc/mkinitcpio.conf`. (Manually placing the pango font into the initramfs image.)

STEPS TO REPRODUCE

_Note that the issue is observed when entering an encryption password, so that first must be enabled on the system._

1. Install plymouth and breeze-plymouth
2. Enable breeze theme with plymouth (via plymouth-set-default-theme breeze or config files)
3. Update HOOKS in /etc/mkinitcpio.conf to include plymouth
4. Rebuild initramfs and reboot

The font will be broken and show the white boxes/tofu symbols. This is fixed if /usr/lib/plymouth/label-pango.so is added to BINARIES in mkinitcpio.conf.

OBSERVED RESULT

The text input box for the encryption password shows `▯` symbols or nothing at all.

EXPECTED RESULT

The text input box for the encryption password shows `•` symbols.
