담에 시도해봐야지. 그나저나 server edition만 지원하나? 죄다 CLI로 되어있네?
그런데.. boot 파티션도 raid가 되나?
/boot는 raid 1 에서는 존재가능하고, 나머지는 boot 영역만큼은 다른 스토리지에 넣어줘야 하는 듯
Warning: the /boot filesystem cannot use any softRAID level other than 1with the stock Ubuntu bootloader. If you want to use some other RAID level for most things, you'll need to create separate partitions and make a RAID1 device for /boot.
아마 일반 어플리케이션에서는 접근성 대응이 덜 되어 있는데 웹 브라우저에서는 잘 되어 있으니
온갖 말을 하다가 더 난리가 났던 듯.
그나저나 누르고 있으니 이 어눌한 말은 왜케 웃기냐 ㅋㅋ
카테고리 없음 이렇게 한글 비슷하게 읽어주는것도 있긴한데
타자를 막 치고 있으면 이어폰으로 온갖 이상한 소리가 ㅋㅋㅋ

You will be presented with a > prompt. Type
(SayText "Hello")
The computer should say "hello".
To listen to a text file named FILENAME, type
(tts "FILENAME" nil)
Note FILENAME must be in quote marks.
festival 이라는 어플리케이션을 통해서 읽는것 같은데
한글을 넣으면 segmentation fault가 뜨는데
도대체 아까 오른쪽 왼쪽 같은 TTS 음성이 도대체 어떻게 나온걸까?

btrfs는 fsck로 체크 못하고, btrfs 유틸리티의 check 명령을 통해서 확인해야 한다.
# fsck /dev/mmcblk2p9 fsck from util-linux 2.37.4 If you wish to check the consistency of a BTRFS filesystem or repair a damaged filesystem, see btrfs(8) subcommand 'check'.
