Hi,
I am trying to create an auto mounted file system when system is rebooted. I altered the /etc/fstab file and changed the option to "auto".
But after I reboot the system,the fstab file doesn't take affect and the accociated file system option restroed to "noauto".It seem that when system reboot ,the file fstab is rewriten.Following is my file fstab and I didn't change anything.

/dev/hda6 / ext3 defaults,errors=remount-ro 0 1
proc /proc proc defaults 0 0
/dev/fd0 /floppy vfat defaults,user,noauto,showexec,umask=022 0 0
usbdevfs /proc/bus/usb usbdevfs defaults 0 0
sysfs /sys sysfs defaults 0 0
/dev/cdrom /cdrom iso9660 defaults,ro,user,noexec,noauto 0 0
/dev/dvd /dvd iso9660 defaults,ro,user,noexec,noauto 0 0
/dev/cdaudio /cdaudio iso9660 defaults,ro,user,noexec,noauto 0 0
# Added by KNOPPIX

# Added by KNOPPIX
/dev/hda2 /mnt/hda2 vfat noauto,users,exec,umask=000 0 0

/dev/hda5 /mnt/hda5 ntfs noauto,users,exec,ro,umask=000 0 0

/dev/hda9 /mnt/hda9 vfat noauto,users,exec,umask=000 0 0

What type of HD install is is? If it is Knoppix-style, Knoppix re-writes fstab with each boot so it will overwrite your changes. To make it stop doing this, add 'nofstab' to the 'append=' line in /etc/lilo.config then re-run lilo.

Hi CrashedAgain,
Thanks for your consideration.I tried but it does not work.First,I updated the lilo.conf file and add 'nofstab' after 'append='.Then i ran lilo and updated auto option of file system in the fstab file.Then i reboot the system. I checked the fstab file and it is rewriten by system.
What i used is Knoppix 3.6 HD instal.I am wondering.

Hmmm. It should have worked. post your /etc/lilo.conf file. I'm sure the nofstab option is the same in Knoppix 3.6 as in 3.4.

Hi CrashedAgain,
Followings are my lilo.conf file.There is a little different from yours.Thanks again.

# Note that if you really need this type of security, you will

Never put cheatcodes on this "append" line....It won't work.
Put cheatcode on append line after you declare your image.
Do like Crashed did:


image=/boot/vmlinuz-2.6.6
label="Linux(new)"
root=/dev/hda5
initrd=/boot/initrd.img-2.6.6
append="lang=us apm=power-off ramdisk_size=100000 init=/etc/init nomce nofstab wheelmouse"
read-only

and yours should look like this:

image=/boot/vmlinuz-2.4.27
label="Linux(2.4)-1"
initrd=/boot/initrd.img-2.4.27
append="ramdisk_size=100000 init=/etc/init lang=us apm=power-off nomce quiet nofstab"
read-only

:D :D

It seem that when system reboot ,the file fstab is rewriten.


Only the part of the file after the first line "#Added by KNOPPIX" is rewritten.

So make changes above that line, like this:



/dev/hda6 / ext3 defaults,errors=remount-ro 0 1
proc /proc proc defaults 0 0
/dev/fd0 /floppy vfat defaults,user,noauto,showexec,umask=022 0 0
usbdevfs /proc/bus/usb usbdevfs defaults 0 0
sysfs /sys sysfs defaults 0 0
/dev/cdrom /cdrom iso9660 defaults,ro,user,noexec,noauto 0 0
/dev/dvd /dvd iso9660 defaults,ro,user,noexec,noauto 0 0
/dev/cdaudio /cdaudio iso9660 defaults,ro,user,noexec,noauto 0 0

# Put your changes here
/dev/whatever /mountpoint ...

# Added by KNOPPIX
/dev/hda1 /mnt/hda1 ntfs noauto,users,exec,ro,umask=000 0 0

....


Then you will still get the nice feature of Knoppix adding lines to your fstab - for example, if you have a USB drive plugged in when you turn on the computer, Knoppix will add a line for it in fstab and you can access it using a desktop icon.

Also, with my version (3.4) I had to change the system initialisation sequence for the drive to actually be mounted, by doing the following in a console:


su root
ln -s /etc/init.d/mountall.sh /etc/rcS.d/S39mountall

Hi,
I tried two ways you recommended.For my case,the update of lilo.conf doesn't work and the update of fstab works.now I know that the comment line "Added by knoppix " in fstab file is not only a comment.
Thanks both of you for help.
