SITUATION:
For certain reasons, I replaced my swap partition hda6 with
a swapfile. I then changed the partition type of hda6 to
Linux instead of 'Linux Swap'.I ran mke2fs on hda6. Now I
have a 70M filesys. I revised the /etc/fstab entry for hda6
to type 'ext2'. It mounts without any problems.
QUESTIONS (in order of priority):
1) What is the minimal set of files I need to boot single-user
off hda6 (with 'root=hda6') from the grub command line?
I don't mean grub config files, I mean 'vmlinuz', and what else?
2) In order to boot off hda6 (I am getting my bootloader
off a floppy) do I have to make hda6 'bootable' in the
partition table?
3) Will making 'hda6' bootable override or toggle the bootable
status of my original root partition 'hda5' (Both are ext2) ?
I believe the answer to be 'no' but I would like to be sure.
4) What is the best way to save a partition table beside the
following (from the sfdisk man page):
-I file
After destroying your filesystems with an unfortu
nate sfdisk command, you would have been able to
restore the old situation if only you had preserved
it using the -O flag.
No, this hasn't happened to me..
The above only works when 'sfdisk' is used to make the
changes and I prefer using something less powerful than
'sfdisk'.
5) Finally consider the following:
$sfdisk --list | grep hda'[25]'
Device Boot Start End #cyls #blocks Id System
/dev/hda2 3 2481 2479 19912567+ 5 Extended
/dev/hda5 3+ 2472 2470- 19840243+ 83 Linux
Why does hda2 begin 9 cyls later than hda5, overlap almost all
of hda5 and end 9 cyls earlier?
