Не видел, чтобы правили корень в /etc/fstab после dd.

Ввиду отсутствия опыта, даже и не догадывался что нужно :)

Сейчас поправил. Перезагружусь проверю.

И так правки fstab маловато, есть еще в mtab. Но в /etc/ есть файл @mtab , через mc F3 позволяет посмотреть содержимое, а F4 показывает пустой файл. Как его править?
Еще попробовал запустить gedit от имени администратора, перетянул @mtab, содержимое вижу, но править не могу... Видимо совсем не то делаю :(

Вот и источник, откуда df берёт корень:


# strace -eopen df -l
...
open("/etc/mtab", O_RDONLY) = 3
...

Править нужно fstab, а mtab -- штука динамическая, не обращайте внимания, если правильно путаю, его и удалить можно, переименуйте во что-нибудь и перегрузитесь.

"man mount" написал:

The programs mount and umount maintain a list of currently mounted filesystems in the file /etc/mtab. If no arguments are given to mount, this list is printed.

Символ @ -- это не часть имени файла, а условное обозначение того, что это симлинк на файл, на какой именно видно в министатусе панели в mc или в выводе ls -l /etc/mtab.
/dev/root тоже должен последовать за fstab, если нет, то пересоздайте ссылку руками.


ps. Переключение на реальный корень производится из initrd, не знаю как оно в SUSE устроено, но вероятность того, что корень прибит гвоздиком внутри initrd далеко ненулевая.

Кстати переименование и помогло.
