# ls -l /dev/disk/by-partlabel/protoroot
lrwxrwxrwx 1 root root 15 May 4 18:41 /dev/disk/by-partlabel/protoroot -> ../../nvme0n1p2
# mount /dev/disk/by-partlabel/protoroot -o subvol=/alt /mnt
# btrfs subvolume get-default /mnt
ID 671 gen 9498169 top level 5 path debian
#
# cat /mnt/etc/initrd.mk
# trying to detect modules and features to access to root volume
AUTODETECT = all
MODULES_TRY_ADD +=
FEATURES += plymouth btrfs
Мне надо, чтобы можно было загрузить альт с корнем на btrfs-подразделе.
У меня в /etc/fstab написано следующее:
# cat /mnt/etc/fstab
proc /proc proc nosuid,noexec,gid=proc 0 0
devpts /dev/pts devpts nosuid,noexec,gid=tty,mode=620 0 0
tmpfs /tmp tmpfs nosuid 0 0
UUID=a8c68183-f5bf-4623-86fe-41d9171b7c5f / auto subvol=/alt,relatime 1 1
UUID=a8c68183-f5bf-4623-86fe-41d9171b7c5f /home auto subvol=/home/:alt,relatime 1 1
PARTUUID=c08f5c6b-3fe3-4c94-ab53-4efd654b617d /boot/efi vfat umask=0077,dmask=0077 0 1
После регенерации initramfs, её установки в загрузчик и перезагрузки
система грузится в правильный раздел, но с неправильными опциями
(монтирует подраздел по умолчанию).
# chroot /mnt
(chroot) root@cello / # rpm -qa make-initrd
make-initrd-2.16.0-alt1.x86_64
(chroot) root@cello / # ^D
features/btrfs/README.md, man make-initrd ни на что не наставляют.
Как это побороть?
P.S. Я, правда, пока не пробовал задавать rootflags — но почему бы
make-initrd по умолчанию не взять их из fstab?
