BtrFS ant root

Windows,
Panorau isbandyti BtrFS ir pasirinkau tam OpenSuse, bet nesu tikras kaip elgtis su grub.
Gal teko bandyti paciam ?
Ar reikia kurti atskirai ir /boot (ext3/4) ?

Nustaciau BtrFS tik ant root ir gavau perspejima:

Gal turi patarimu, pasiulymu nes nelabai turiu noro kurti atskirai /boot. Aciu!

Perspejimas buvo teisingas

There was an error generating the initrd (1)

Bet tikiuosi veiks ir tokiu budu

linux:/home/linux # grub2-install -f /dev/sda                                                                              
Installation finished. No error reported.

Ne as asmeniskai atskira boot su ext3 dariau, galvojau kad taip geriau ir saugiau.

Ok, bandau ir as taip (teko sunaikinti buvusi /home).

Format partition /dev/sda5 (1.19 GB) for swap
Format partition /dev/sda6 (1.18 GB) for /boot with ext4
Format partition /dev/sda8 (47.42 GB) /home with btrfs
Format partition /dev/sda7 (49.35 GB) / with btrfs

Gal dabar bus viskas gerai, ir tikiuosi greitu laiku grub palaikys BtrFS.

Vis dar nesekmingai. Atradau dvi bedas (tikiuosi visas)
1: kai tik paleidzia grub monitorius uztemsta ir paraso "Frequency Out of Range".
2: bootinasi ~ 2min ir atjungia keyboard, tai turbut Xorg problemos...

Del Xorg tai visai normalu, bet ka daryti su grub?

grubo parametrai blogai nurodyti, cia del frequency out of range. Greiciausiai tau reikia nurodyti kitokia rezoliucija su grubu.

Bet siaip nelabai suprantu, jei tarkime opensuse nepalaiko instaliacijos i btrfs, tai yra kitu distribuciju kurios tai sugeba. As asmeniskai buvau instaliaves su grafiniu instaleriu tiek fedora 16 (is DVD), tiek calculate linux tiesiai i btrfs ir niekur nieko blogo nebuvo.
Tuo labiau kad fedora kaip ir skaitosi labiau "bleeding edge" linux distribucija nei opensuse tai speju btrfs bandyti butu geriau su ja.

Tavo tiesa, /boot/grub2/grub.cfg buvo nustatyta set gfxmode=2400x1900 ar panasiai. Dabar veikia viskas tikrai gerai net su nouveau Gallium driveriais.

O tokios problemos greiciausiai del to, kad opensuse rasausi beta.
