I'm searching for months (if not years) now for a solution to the following problem:
I wish to have a general setup based on the following:
PC/Laptop/Notebook/Server with ...
1 (ONE) S-ATA CompactFlash DRIVE (8/16/32/64::GB) to hold any linux-partitions needed to deliver a fully running system with root access, BUT avoiding temporary partitions (like for updates,installs, downloads etc.) - just the full CORE running independent, but far better when combined with the following Part [B] ...
1 (ONE) S-ATA HardDiskDrive (HDD) holding any temporary partitions needed to make linux running more efficient (as mentioned under [A] delivering temporary space for downloads/updates/installs) - IF POSSIBLE it should be usable with MBR-Partition-Type, so that free-space can be used for Windows/NTFS and a direct boot via BIOS-Boot-Order/GRUB2 is possible
1 (ONE) PCMCIA CompactFlash Adapter to bind encrypted /HOME-Partitions and User-Specific settings, which should (if possible) be shown up at login screen in the moment one of it is present (like late-binding of user-specific-data and account-settings, maybe delivered via steady request on hot-swapped pcmcia-device?)
Is it possible?
Please don't do me harm, by giving me instructions on how i could enable a much more secure or insecure, but faster and more reliable way. It's my mixture and i ask you freaks and geeks who have much more competence on this subject than me, for advice.
Is it possible to do a late and reactive binding of encrypted /HOME-partitions and USER-ACCOUNTS?
Is it possible to separate (mostly) READ-ONLY-DATA and (mostly) TEMPORARY-DATA on two physical drives?
If so, please give me the answer. And even if it is not possible with Ubuntu (hopefully with Oneiric Ocelot) than maybe it can be accomplished with pure DEBIAN or with concurrent LinuxOS like CentOS or Fedora?
In case, i misunderstood something in general, relating the boot- and or- system/-core-procedures of LINUX, please leave an explanation.
P.S.: If you can't understand, why this is important: I realized that Compact Flash Type III Cards deliver much more responsiveness and reliability than HDD or SSD, measured over 3 years experience, by now. And i believe - in physical - it is the best way to make such systems human-compatible -- maybe you should take a deeper look at the measurements of pcmcia-compactflash-adapters if you doubt it (ever thought of credit- and identity-cards and endurance of memory?)
In hope i made your heads stumble and i am earning constructive response on this request, i leave with best regards to all of you who think of it before denying.
