I have a frugal install on hda1 with hda2 as backup restore hda3 for data
I need to remount my hda1 with to edit the grub menu I used code [/opt]# sudo mount /dev/hda1 mount: /dev/hda1 already mounted or /mnt/hda1 busy mount: according to mtab, /dev/hda1 is already mountd on /mnt/hda1 [/opt]# sudo mount /dev/hda1 -o remount,rw
I think every thing is well and open grub/menu.lst with nano make the change and try to save and get the error can not save read only file system
then use mount command
[/boot/grub]# mount /dev/root on / type ext2 (rw) /dev/hda1 on /cdrom type ext2 (rw) /dev/cloop on /KNOPPIX type iso9660 (ro) /ramdisk on /ramdisk type tmpfs (rw,size=46668k,size=209331k) /proc/bus/usb on /proc/bus/usb type usbdevfs (rw,devmode=0666) unionfs on /bin type unionfs (rw,dirs=/ramdisk/bin=rw:/bin=ro) unionfs on /dev type unionfs (rw,dirs=/ramdisk/dev=rw:/dev=ro) unionfs on /etc type unionfs (rw,dirs=/ramdisk/etc=rw:/etc=rw) unionfs on /lib type unionfs (rw,dirs=/ramdisk/lib=rw:/lib=ro) unionfs on /sbin type unionfs (rw,dirs=/ramdisk/sbin=rw:/sbin=ro) unionfs on /usr type unionfs (rw,dirs=/ramdisk/usr=rw:/usr=ro) unionfs on /var type unionfs (rw,dirs=/ramdisk/var=rw) /dev/hda1 on /mnt/hda1 type ext2 (rw,nosuid,nodev) /dev/fd0 on /mnt/floppy type vfat (rw)
to me it looks like hda1 is read write what am I doing wrongI think after the inclusion of something.. (was it mount or unionfs or something other?), mounting a partition twice as rw wouldn't work for me.
Since it's already mounted anyways (it seems you are using the frugal bootcode) please edit /cdrom/boot/grub/menu.lst (which was answered many times)yes I know the issue about removing frugal from boot line has been answred time and time again. take a look at what I have here
This sets the default entry to boot. # Remember that GRUB counts from 0, so 1 is the second entry.
default 0
# This sets the length of time in seconds that grub will wait for the user to s$ # before it boots the default on. I recommend at least 15 seconds.
timeout 0 hiddenmenu
# Enter the entry for DSL here. Something like this.
title DSL fb800x600 kernel /boot/linux24 root=/dev/hda1 pictures=/mnt/hda3/Pictures scripts=/home/d$ initrd /boot/minirt24.gz
as I said in my original post I can't change things in my boot menu I get the error message mounted read only. I can change the boot menu on /cdrom/boot/grub/menu.lst but this does me know good because anything that I add doesn't change the boot for example I could change the default time to zero and still get the same 3 seconds that was there before. I then looked and found that there is another boot file that is just /boot/grub/menu.lst this is the on the computer is booting off of and I can not change, that too has frugal removed from the boot command menu.

/dev/hda1 on /cdrom type ext2 (rw)
Looks like it's rw though...
The one in /cdrom is on your hard drive, whereas the one in /boot is one of the templates in /KNOPPIX/KNOPPIX - they are unrelated.
You've just got to try it...?
One problem that I can guess: if you're actually _not_ booting off hda1 and stage2 grub is on another partition you need to edit that one instead.
