Yo,

Frugal grub installed after a bunch of retries; I set some options, later wanted to redo the options to set home, opt, mydsl, restore, and host. On my first install that actually worked, the script prompted me for boot options. But never again.

I tried editing grub's menu.lst, but it's read only (must have been the copy in RAM, not sure where the editable copy lives).

I tried reinstalling DSL, but script didn't offer to let me set boot options this time.
I tried running the install script using the update option instead of install, but still no prompt for boot options.
I tried feeding options to grub at its command line at boot time, booted up, checked menu.lst, my new options don't appear there.

I'm using the frugal grub install script from within the fluxbox wm. BTW, where can I find that script in the file system? I'd like to read through it.

You need to edit the menu.lst that's in the root of the installed partition like /mnt/hda1/boot/grub/menu.lst. You have to do that as root. Sounds like your trying to edit the one that's in the filesystem at /boot. That should get you what you need.

As far as the boot prompt goes, you can edit grub entries at runtime. This is for the current session only; the changes are not saved to disk.

1) Select a Grub entry when the list appears at boot time.
2) Press "e" to edit.
3) Select the line you want to edit (if there is more than one line).
4) Press "e" to edit.
5) Press "Enter" to accept changes, or "Esc" to cancel.
6) Press "b" to boot the selected entry.

Chris, thanks for that info. I may need just a bit more of a nudge to get there, tho.

/dev/hda1 = swap
/dev/hda2 = installed partition
/dev/hda3 == where I hope to put persistent stuff

cd /mnt
ls -lR *

Every directory is empty, including /mnt/hda2. Do I need to manually mount to \mnt? I guess I expected that would be automounted. I have used mount command before, but how do I do so in this ramdisk environment?

BTW, I see you are in Indiana. I'm in Indianapolis.

mikshaw,

Right, that's the procedure I used to add the boot options thru grub's cmd line. You confirmed for me that options entered that way do not save. Thanks.
