[SOLVED] Modifying boot splash

[xtsimpouris]

Got happy too soon. Today system showed this error (attached pic):

Terminal

To dropdown to shell, hold shift on usb attached keyboard...
Loading initram modules ...
Mounting root as: mount -t btrfs -o rw,subvol=root/@,noatime,compress=izo,thread_pool=1,space_cache,autodefrag /dev/mmcblk0p2 /rootfs
mount: mounting /dev/mmcblk0p2 on /rootfs failed: Invalid argument
Mounting root partition /dev/mmcblk0p2 failed

BusyBox v1.20.2 (Debian 1:1.20.0-7) built-in shell (ash)
Enter 'help' for a list of built-in commands.

/bin/sh: can't access tty; job control turned off
/ # _

To be honest, I don't know if this error is relevant to this thread. However, as this error was shown after a clean installation and just making the above procedure to change the pic, I post it here to be crawled for others. At this point (new installation), I won't make any change at all to see how it goes and post back again if I have any news!
