Booted existing core20 vm with old grub2. rss went up from 128264 to 422636, after executing loopback loop1 (hd0,gpt2)/snaps/pc-kernel_565.snap.
Replacing grubx64.efi with the one from grub-efi-amd64-signed_1.142.5+2.04-1ubuntu26.3_amd64.deb.
loopback command was very quick, and rss went up from 129244 to just 129452.
So this is good!
