I usually share /var/mail between releases.  It seems to be compatible 
between releases (at least it has been for more than a decade), and this 
keeps mail from getting lost by arriving when the wrong release is in 
use.

   appear in the mount point table (eventually in fstab of the new
   install). I think what you are telling it is that you want sda1 to
   mounted as / IN THIS INSTALLATION and that then clashes with your new
   / (on sdc) that you're trying to install to.

     In the partitionner (which is not only a partitionner, but generates the
fstab and the filesystems), you should select "dont use the partition"on
every partition which is not in sdc. Click on "use partition  as"  and
select  "dont use the partition".

Didier, that seems to have done the trick. I apologize for having been
too hasty. Where the partitioner asks what to use a partition as, because
the top options were simply file systems, I interpreted it to be merely
for selecting file system and did not notice the "don't use" option at
the bottom. When I marked sda partitions not to be used, I was able to
save the sdc partition table and proceed with the installation.

Now that installation of ascii 2.0 on sdc is underway and before going
further I must figure out how to recover a use of partitions on sda. I
assume that were I to use the menu to revert to partitioning and restore
usage of sda partitions I'll just end up with the same problem of a
competition of sda and sdc for use of /.

When I execute a shell toward the end of installation, can I use it to
run the command "parted /dev/sda set 1 boot on" both to enable sda1 and
to make it bootable at the same time? Would the command "parted /dev/sda
set 2 on" simply re-enable the second partition? I found the parted
manual unclear on this point.



    I guess you don't want to use sda from your sdc OS. Therefore don't 
do anything more. When you boot the OS on sda, then, this one won't use 
sdc. And vice-versa. Isn't this what you want? Or do you haved changed 
the partition table on sda, or erased some partitions there which you 
want to recover? This can be difficult.


    If you want to share a partition (say home) between different OSes, 
then, of course you have to mention it, but it's not recommendable 
because config files of several applications are not backward compatible 
between versions. Also private applications using dynamically linked 
libraries might not find the proper version of the libraries. But of 
course, it is convenient to mount the old home from another disk to copy 
it to the new one to start from.

I am fairly sure you will need to set up grub2 to do this, try reading

Or failing that, google for the answer ;-)



    When your installation is almost finished, one of thevery last 
steps is installing the Grub bootloader. Just do it: it will 
automatically detect all OSes on all disks (which don't need to be 
mounted in any way), and generate a boot list which enables all them. 
You will have the currently installed OS on top of the list, then a 
rescue mode for this OS, then all the other detected OSes. You decide on 
which disk you want to install the Grub bootloader. I suggest you 
install it on all disks as explained below.


 You can install the Grub bootloader on other disks as well, either 
by re-running the bootloader installation step (I didn't check but I 
don't see why it would fail), or by invoking install-grub from the 
command-line (install-grub /dev/sda; install-grub /dev/sdb; etc..).


    Grub does not use internally the device names sda2, sdb1 sdc5, 
etc... but the UUIDs of the partitions to boot from, therefore you can 
permute your disks as you like if you have installed the bootloader on 
all of them.

This is exactly why modern d-i and grub use those unsightly UUIDs instead of
user-friendly "sda".  You don't want the system to break just because you
removed one of the disks, or this time one of them took a few seconds longer
to spin up and thus lost a race.

Yes. In the past I've always had multiple hard drives in one machine,
each with an operating system and its own boot menu. This because I've
become paranoid over the years and always want the option of which drive
on the machine to boot.

I suspect, though, that these disks always had at least different
versions of the operating system, and what I'm doing now is trying to
install ascii 2.0 on a disk in a system that already has a disk with
ascii-rc on it. Do you know if I wouldn't have had the problem had I
tried to install devuan testing or experimental on sdc with ascii on
sda?

The suggestion to disconnect the sda drive while I install the same
version of the operating system on sdc occurred to me, but I worried
about the effect of the resulting change in drive designations. In my
case, by disconnecting sda my sdb becomes sda and my sdc becomes sdb.
Will all of this sort itself out when I reconnect the old sda drive and
boot it?  After installing ascii on sdc I probably will have to select
sda as the drive to boot in BIOS and then run update-grub after it is
up.

Don't underestimate my ability to get confused, especially when a
practice I've followed for years no longer works. It may be the
difficulty arises now because two of the machine's disks are for ascii
(one rc and the other stable), and jessie is on sdb. Does the conflict
over use of \ only happen if operating system versions happen to be the
same? If so, I wonder if an expert installer could be warned of this and
what to do about it. For example, the error message that pops up could
be more informative. 

In the partitioner, when I go to edit a partition, one option is to "use
as:" If I specify to use as ext4, then the additional
settings become available of whether to format the partition and set its
mount point. If instead I chose "do not use", I no longer have the
option to format and define a mount point.

That is as you say, but your comment about watching out for GRUB later
on in the installation worries me. You warn me that I should not allow
grub to "damage" (confuse?) the grub on sda, but the installer asks a
question that I do not find to be clear.  When installing GRUB and after
the installer discovers what operating systems happen to be accessible
for the installation, it tells me it is safe to install GRUB in the mbr
of the first drive, which in my case is sda. My intent is to leave GRUB
as it is on sda and to install it instead on sdc. However, it then asks
whether to install it in the mbr. To which drive does this refer?  Is it
asking if I want to install GRUB in the mbr of the first drive, sda, or
is it asking simply whether to install GRUB the mbr on whatever drive I
next install GRUB?

Didier, that seems to have done the trick. I apologize for having been
too hasty. Where the partitioner asks what to use a partition as, because
the top options were simply file systems, I interpreted it to be merely
for selecting file system and did not notice the "don't use" option at
the bottom. When I marked sda partitions not to be used, I was able to
save the sdc partition table and proceed with the installation. 

Now that installation of ascii 2.0 on sdc is underway and before going

assume that were I to use the menu to revert to partitioning and restore
usage of sda partitions I'll just end up with the same problem of a
competition of sda and sdc for use of /.

When I execute a shell toward the end of installation, can I use it to
run the command "parted /dev/sda set 1 boot on" both to enable sda1 and
to make it bootable at the same time? Would the command "parted /dev/sda
set 2 on" simply re-enable the second partition? I found the parted
manual unclear on this point.

I think you may be confused about what this section is doing.

You are telling the installer a) what to do with a disk & it's partitions (eg, 
should it format a partition), and b) where they should be mounted.

So for your partitions on sda, you tell it NOT to format them and not to mount 
them anywhere - I certainly recall those being options in the Debian installer, 
you may need to go into expert mode. Alternatively, tell the installer NOT to 
format them and set a different mount point (eg /jessie, /jessie/boot, ...)

When you set a mount point, it's telling the installer two things : where to 
mount the filesystem during the install, and what to put in the installed 
system's fstab. If you tell it to do nothing with the partitions/filesystems on 
sda, then they will simply be left alone - but watch put for grub install later 
on, you don't want to damage the grub that's already installed.

So don't format the partitions on sda, don't mount them anywhere, and you'll 
end up with a new install on sdc that just ignores the system already on sda - 
but as mentioned, be careful when it comes to grub install time.

Then (I assume through the system BIOS) you'll be able to boot using the old 
system & it's grub on sda, or the new system & it's grub on sdc.

In "typical usage:" option when configuring the root partition, there is
no option that would disable it. In any case, I don't want to disable
it, but to be able to boot any disk and use its grub menu to boot it or
any other disk. I've always been able to do that.

It occurs to me that I could simply disconnect the SATA cable from my
sda and then partition sdc and after installation reconnect sda and run
update-grub on the disks. But I hesitate to do it because then the
sda/sdc identity of the disk would change and I might end up unable to
boot either disk. Another approach might be to boot sda run fdisk on
sdc and then do an installation on sdc without partitioning it.  

Incidentally, on sdb I have have installed an old Debian (Etch?). When I
try to partition sdc it does not want to use its root partition. only
the root partition of sda. I suspect something has changed between
Jessie and Ascii.

The partitioner in devuan install I suppose is parted, but not sure.

You are using fstab and assigning the partitions how you want them to be 
used?

You probably want to set this partition to unused (or whatever it's called, 
it's a looong time since I last did this) so that it doesn't appear in the 
mount point table (eventually in fstab of the new install). I think what you 
are telling it is that you want sda1 to mounted as / IN THIS INSTALLATION and 
that then clashes with your new / (on sdc) that you're trying to install to.

Thanks, Didier, 

In the partitioning scheme, sda is HD ST1000DX002-2DV1. It has a primary
partition that is bootable and the mount point /. When I edit this
partition, it says it is on sda. 

Disk sdc is ST1000MN0011, and it also has a bootable partition #1. When
I edit it, it says I'm editing disk ST1000MN0011 partition #1 of sdc. I
give it / as mount point, make it bootable, and the label "root". 

Partition #1 on sda is has mount point /, the mount options I leave as
the defaults, label I left out the label, but now label it "root". This
should make no difference as far as I can see. I leave typical
usage as "stardard". I don't know what standard options refers to, but I
should think standard option would not cause this disk to interfere with
others.

But I get the error, "Identical mount points for two file systems."

    First, check carefull y what you do in the partitionning dialog. 
sda shouldn't be used at all by the system you install, but I suspect 
you have maybe marked it as used in some way.
