 Gujin is working for you, i.e you have installed it=0Aon a floppy, a USB k=
ey or a CDROM and it does what you want;=0Aso (as a next step) you want to =
install it on your hard drive.=0A Basically, Gujin just needs the first sec=
tor of the disk (MBR) or=0Afirst sector of an active partition, plus some s=
pace in a filesystem.=0A The filesystem could be anything but only FAT is i=
mplemented=0Aright now (by lack of time), and because I am used to only use=
=0Aa B.E.E.R. partition (containing a FAT) to install Gujin.=0A The B.E.E.R=
. partition can be very small, some disk partition=0Amanagement systems lea=
ve few hundred Kbytes to few Mbytes=0Aat end of the drive by default and th=
at is enough for Gujin.=0A Then, you just need to boot Linux and type as ro=
ot:=0A./instboot boot.bin /dev/hda0=0A if you want to install on disk /dev/=
hda. It will automatically search=0Afor some free space at end of the disk =
to create this B.E.E.R.partition,=0Aand if correctly found will ask you to =
confirm before writing to the=0Adisk. If you say "yes" the installer will s=
et up the end of the disk=0A(creating a small FAT partition there) and the =
install finish=0Ausually without any problem.=0A The main advantage of the =
B.E.E.R. partition is that it does not=0Atake a slot in the partition table=
.=0A My advise is to use the previous system by default, often you just=0An=
eed to reduce the last partition by one or two cylinder, easy if that=0Apar=
titon is for swap space.=0A=0A Note the "-hx" option of instboot which desc=
ribe usual installations.=0A=0A> And then this device (/dev/hda4)=0A> ./ins=
tboot boot.img /dev/hda4=0A>                     ~~~~~~~~~=0A> refers to th=
e special gujin partition?  Is that right?=0A> (so that I need to go reinst=
all Linux and create that partition)=0A=0ANow if you have an empty slot in =
your partition table (primary or extended),=0Awith some free space on your =
disk, like /dev/hda4, you can use it.=0ANote that it is not a "special guji=
n partition", there isn't such a thing,=0Abut the installer create a FAT fi=
lesystem, inserting a bootloader;=0Ayou will be able to use that FAT filesy=
stem anyway you like after creation.=0A=0A> Q2.  Does gujin have scriptable=
 capabilities?  E.g., with=0A> lilo, I can build a new kernel, copy it to /=
boot, and tell=0A> lilo to boot the new kernel *one time only* on the next =
boot=0A> (-R option).  This makes installing & booting a new kernel=0A> ver=
y safe, which is important when doing lots of kernel builds=0A> and testing=
.  I suppose another way to ask this is:=0A> can I tell gujin to boot a spe=
cific kernel on the next boot?=0A> and can that be in effect only one time?=
=0A=0A To create a one-shoot only boot process, you need write access=0Ato =
the hard disk (to store that you have booted once), and Gujin=0Acan be conf=
igured to not write at all (by default).=0A In fact, because it is so easy =
to select which kernel to boot, I never=0Aneeded this function.=0A I have i=
n between 3 and 7 Linux distribution on the same PC, the work=0Apartition h=
as up to 10 different kernel version at the same time, so=0AI like to keep =
the boot process simple and select which kernel with=0Athe mouse.=0A=0A> Q3=
.  Does gujin work on x86_64 systems?=0A=0ACannot test, I do not have x86_6=
4.=0A=0A> Q4.  What does "hda0" in the FAQ refer to?  Linux doesn't use=0A>=
 that naming scheme.=0A> Oh, that's the BEER partition.  Is that required?=
=0A> (I could probably answer that by reading the FAQ or install.txt,=0A> b=
ut install.txt seems much too rambling IMO.)=0A=0A The B.E.E.R. partition i=
s not needed (and you will not use that=0Aon a USB key, a CDROM or a floppy=
) but that is what I use=0Aas default on a hard disk, because it is simpler=
 - as described=0Apreviously.=0A Either write down better bootloader or mor=
e docs, I am more=0Ainterested by better code; moreover people ask me to co=
mpare=0Awith Grub or LILO and I did not use any other bootloader than mine=
=0Afor the last 5 years - so I can't compare.=0A=0A> Q5.  Several examples =
in install.txt use "boot.img" as a filename.=0A> Is that supposed to be "bo=
ot.bin"?=0A=0A Yes, thanks I will correct. I have changed the extension in =
Makefile=0Aaround version 0.6.=0A=0A> Thanks,=0A> ---=0A> ~Randy=0A=0A Than=
ks for testing Gujin,=0A Etienne.=0A=0A=0A=09=0A=0A=09=0A=09=09=0A_________=
