devfs -> udev, hogyan?

Linux-kezdő

Hali!

Ma reggel telepitettem egy (K)Ubuntu-t (5.10) minden oke volt, orultem hogy latja az NTFS particiokat is, aztan fogtam magam es forditottam egy uj kernelt (2.6.15.6) es innentol kezdve csak azt az 1 vinyot latta amin maga az OS van.

Bootolaskor: mount: unknown filesystem type: 'devfs'

Arra sikerult rajonnom hogy a devfs-t kene lecserelnem mivel ebben a verzioban ha jol tudom mar nincs benne es helyette az udev-et kene hasznalnom, mar csak annyi problemam van , hogy , hogy kene atallni? udev telepitve van (apt-get install udev) devfsd torolve van de a problema meg mindig fennall.

Elore is kosz a valaszokert.

Csak azért fölösleges udev hogy a fájlrendszereket automatikusan felcsatolja. Nézd meg mi hol van
fdisk -l
és írs át az /etc/fstab-ot
pl. :
/dev/hdb4 /mnt/hd2 ntfs ro,auto,umask=022 0 0

# /etc/fstab: static file system information.
#
#

proc /proc proc defaults 0 0
/dev/hdc3 / ext3 defaults,errors=remount-ro,atime,auto,rw,dev,exec,suid,nouser 0 1
/dev/hdc6 none swap sw 0 0
/dev/hdd /media/cdrom0 udf,iso9660 user,noauto 0 0
/dev/fd0 /media/floppy0 auto ,atime,noauto,rw,dev,exec,suid,user 0 0
/dev/hdc5 /home/dani/g ntfs ,uid=1000,gid=1000,auto,rw,owner 0 0
/dev/hda1 /home/dani/f ntfs ,uid=1000,gid=1000,auto,rw,owner 0 0
/dev/hdb1 /home/dani/d ntfs ,uid=1000,gid=1000,auto,rw,nouser 0 0
/dev/hdc1 /home/dani/c ntfs ,uid=1000,gid=1000,auto,rw,nouser 0 0

ez igy lehet jo?

ilyen az fdiskem:

az fstabból szedd ki a többi bejegyzést az fd0-ról, elég egy is.
más: próbáld meg a következőt: létrehozol egy könyvtárat az /mnt-ben normális jogokkal: mkdir /mnt/d
chmod 0755 /mnt/d

"Thats because devfs is creating the nodes in kernels < 2.6.14.
With 2.6.14 DEVFS is no longer supported in the kernel, so you have
to use another method to create device nodes like udev (the new way)
or MAKEDEV( the old way, before devfs)."

so you have to use another method to create device nodes like udev - ezt hogy lehetne megvalositani?

Problema megoldva, random allitgatos kernelbe googlezas utan, hibauzenet megmaradt de mar mountol mindent, asszem ezt a kernel configot elmentem ^^ thx a helpet mindenki
