#osk-sdl unlocking a LUKS rootfs running PureOS on the #purism #librem5 devkit.

osk-sdl is an initramfs touchscreen keyboard made originally for postmarketOS, for unlocking a LUKS rootfs on touchscreen devices with no physical keyboards.

The long unlocking time is due to the rootfs being encrypted on a big core desktop system (see `man 8 cryptsetup` /--iter-time)
