</div>The installer is configurable to the extent that any distribution's<br>
installer iso is configurable. You just need to know where the<br>
installation components are and how they interact.<br>
<br>
The origin of my question to the list arises from the hints of md<br>
support already in the places within the installation.<br>
<br>
After ISOLINUX expands the initrd and finds its proxmox iso image, the<br>
init script invokes /sbin/unconfigured.sh on the ISO mount.<br>
<br>
In the final acts of /sbin/unconfigured.sh, there's a commented-out line<br>
to shut off md device md0, indicating that there was once a time when it<br>
was enabled.<br>
<br>
But there's quite a bit more: For example, after proxmox finds the<br>
installation media and starts up X, the installation contiues from<br>
openbox/.xinitrc to invoke /usr/bin/proxinstall.<br>
<br>
Within the /usr/bin/proxinstall script, one finds this code in the<br>
probing for disks:<br>
<br>
foreach my $hd (@$hds) {<br>
my ($disk, $devname) = @$hd;<br>
next if $devname =~ m|^/dev/md\d+$|;<br>
print "found Disk$disk N:$devname\n";<br>
}<br>
<br>
So the installer is specifically excluding md devices when looking for<br>
disks.<br>
<br>
Naturally this begs the question of what would happen if one added<br>
modprobe's for md raid support (right after the modprobe of dm_mod in<br>
unconfigured.sh), removed the "next if..." line in the proxinstall<br>
script above, reconstituted the ISO, and booted it up to "see what happens."<br>
<br>
It seems that someone else had probably already done this. If no one<br>
else has done it then it's likely someone would be willing to offer<br>
advice on why enabling support for md devices would be "a bad thing(tm)"<br>
or at least offer some insight as to why md devices are specifically<br>
avoided in the present installer.<br>
