@_bapt_

yay, ty!

(I still say running ZFS on 256 MB is daft at best, but reducing memory is good.)

@mwl I have managed to already divide by 2 the amount of memory necessary to install FreeBSD-src package (the memory peak highly depends on the number of files).

@mwl after this change: https://github.com/freebsd/pkg/commit/83243c7894afd319f009cc9135cc461767deea35 and thanks to #valgrind's massif tool, in a reference jail I used with LOTS of packages (including many package with plenty of files) the maximum memory peak for a pkg upgrade went from 1.4GB down to 199MB!

@mwl Is that in the release notes for FreeBSD itself?

@dexter ah, ty!

256mb might be a perfectly reasonable minimum for many cases, but I can reliably freeze the installer with that little RAM...

@mwl hrm, I know @grahamperrin noted late last year¹ that the documented minimum RAM requirements were insufficient for certain aspects. Sounds like it might be worth noting/updating the vm-bhyve template default in that bug-report²
