real-root-dev je taky trivka. vraci jen device cislo z lstatu struct_fs - jen pro jistotu, aby to bootovalo i kdyz nahodou nekdo zmeni jadro a zmeni se cislo zarizeni.

akorat kdyz disk uplne chcipne neob se vytahne, tak se nedostane pres: mdadm --assemble /dev/md5 /dev/a/raid5 /dev/b/raid5 /dev/c/raid5 /dev/d/raid5 mdadm --assemble /dev/md6 /dev/a/raid6 /dev/b/raid6 /dev/c/raid6 /dev/d/raid6 mdadm --assemble /dev/md10 /dev/a/raid10 /dev/b/raid10 /dev/c/raid10 /dev/d/raid10 mdadm --assemble /dev/md10 /dev/a/raid10 /dev/b/raid10 /dev/d/raid10

mdadm v te verzi co mam rve, ze mu chybi zarizeni... mozna by stalo za to provist upgrade a checknout jak jsou na tom.

pro cistku, aby system po nabehnuti odpovidal tomu co se delo v ramdisku...
