I'd like to help with patches but I'm still not able to code in Guile [3]... I can test it 10 times if that feature will be added :-) Thanks! Gio' [1] actually they are RAID 0 logical volumes created via the "smart array" HP controller software: I was not able (it seems impossible) to configure the controller for direct access of *physical* disks from the OS (HP Smart Array P410 - I **hate** this)... but that's a completely different story... or not? https://serverfault.com/questions/29349/disabling-raid-feature-on-hp-smart-array-p400#41975 [2] https://www.gnu.org/software/guix/manual/en/html_node/Mapped-Devices.html#Mapped-Devices [3] configuring and packaging is easy but it's not the kind of coding we need
