I got around to testing it just now. I used the following netboot mini.iso with -base, -md and mdcfg with your changes included in the initrd: http://nusquama.org/~max/tmp/mdtest1.iso (i386) I'm attaching my notes. To summarize: I did a rather complex setup involving RAID0, RAID1 and crypto and it worked without a glitch. It correctly recovered from partman restarts, retained crypto configuration after configuring RAID and is currently installing the base system. I'll send an update once qemu is finished ;-) The change preventing resize and deletion of partitions on loop-type devices worked fine. Things explicitly not tested: - Inactive/deactiveated RAID devices - I didn't know how to test it. - RAID on crypto (not a useful setup, or is it?) If you'd ask me, I'd say lets commit those changes and make sure to include them in beta3. One risk I'm seeing is that we're effectively enabeling setups that were previously not possible - perhaps there are some bugs to be shaken out. Things like root-on-crypto-on-raid probably need testing. I just remember there was indeed one odd thing: After I finished partitioning the mdcfg dialog came up again. Not sure what was happening there. Max
