50GB on a dedicated LV on LVM [1] (on a foreign distro)

it's very useful when you can _live_ resize your volumes (having enough
free space to allocate): LVM (still not supported in Guix System) and
btrfs are our friends

too small for your usecase?

yes, *if* recommendation should be provided, we should at least figure
out useful classed of use cases (e.g.: Gnome desktop with "office"
applications, guix development workstation,...)

maybe it's not worth the effort?

I need separate volumes for my systems, they are life-savers for me :-)

it would be great to have a similar feature in Guix (I still cannot
help, sorry)


[1] actually I install guix via
(that exits when it find an already created /gnu folder)
*then* copy /gnu content to a LV temporary mounted as /gnu-LV, then "mv
/gnu /gnu-ORIG" and finally mount the LV as /gnu... this does the trick
