I retried from scratch. The md0 would-be-boot partition was correctly set ext2, as indicated below (although it is not clear whether "boot" was accepted:

Because of this some operations may be unavailable. The cause might be a missing software package. The following list of software packages is required for ext2 file system support: e2fsprogs. xxxxxxxxxxxxxxxxxxxxxxx I paid attention to the installation progress, the would-be-boot partition was formatted ext2, however, grub was installed (efi or pc, not clear) automatically, not at request as in the good days of the past. Debian maintainers should recognize that many users in the science area have no time (and no interest) to learn all subtleties of the OS, while they may need updated libraries, and therefore go to testing. They have to follow the scientific literature in their area. That testing installer appears as a testing, which should not at that level. fp ---------- Forwarded message ---------- From: Francesco Pietra <[email protected]> Date: Fri, Jun 6, 2014 at 11:03 PM Subject: Fwd: jessie grub issue To: amd64 Debian <[email protected]> Actually, unlike in my previous wheezy installation, with the testing installer I was unable to install a bootable partition under md0. With wheezy I created a partition of, say, 0.0003TB, primary, beginning, mount point /boot, bootable flag on, using it as physical volume for raid. With the testing installer, when use as physical volume for raid is chosen, bootable flag gets OFF (tried again by deleting partitions and rebuilding raid 1) Consequently, the installer did not ask to install grub. fp ---------- Forwarded message ---------- From: Francesco Pietra <[email protected]> Date: Fri, Jun 6, 2014 at 5:09 PM Subject: Fwd: jessie grub issue To: amd64 Debian <[email protected]> Examining with testing installer, the error followed from errors in configured partitions: LVM VG vg1 etc for md1 ....................................... ........................................
