no one commented, so I did several experimental installs to find out, results here and there in this reply. > I faintly > recall, on my first install attempt, doing that but could only see the > partitions root despite trying to cd up a known path, and when I had > rebooted to wheezy, the partitions were marked dirty and had to be > e2fsck'd which took about 20 minutes with nothing found. Thats not a > very confidence inspiring thing. I found the majority of that networking problem. If during the install, one specs the interfaces address in CDIR format, www.xxx.yy.zz/24 it works, if you give it a separate netmask, it fails. This probably ought to be looked at and fixed, or the installer should be able to detect the missing /24 and spit out a prompt to correct the user. That netmask line is apparently now an error, exiting the e-n-i.d/* file on a reboot at that point, and nothing you do below that line is executed. > Since this WAS a 2 list post, going the emc-developers too since this > install media is theirs, my first attempt used the debian 9.4 1st dvd > for install media, and networking Just Worked.

Which turned into at least 4 more reformat/installs before I was done, finally giving up and only specing 3 partitions. /boot swap and /. And where I found that a wheezy partition can be accessed by the stretch filesystem for reading ok if its mounted with a noatime option. So thats problem #2 solved. I was able to reboot to either without the time killing e2fsck's when booting back into this wheezy. And I finally did a tracking lookup on the new drive hot swap cage, which was a no-show today, and it seems neweggs low cost shipping is by a fedex branded ox-cart, and its someplace in Kansas today with a projected delivery before quitting time Thursday evening.
