Hello, gentoo-users, today I wanted to resize my EFI-partition sda1.
It was on my SSD which had roughly this layout: sda1 300M EFI System sda2 ~460G linux fs -> btrfs sda3 ~4G swap This is a dualboot setup with Gentoo and Fedora (in fact triple-boot as there's some MS Windows 10 Pro on another disk, but anyway) and both distros have their root-filesystems and stuff within the btrfs on sda2. They even share stuff by mounting the same subvols here and there ... nice, by the way. My issue was and is: 300M gets tight when 2 distros install multiple kernels into /boot ... so I would like to have around 500 megs to avoid having to always manually clean up some kernel before upgrades run through. comfort. I ddrescued sda to a HDD for backups, then rebooted with gparted etc etc long story short: it failed. Right now I boot and run from that HDD with still 300M for EFI. sidenote: how slow such a harddisk is ... I'd like to move the full btrfs-structure to a slightly smaller partition on the SSD (which should have that larger EFI-boot-partition) and I would love to get some pointers on how to do that without having any fs-UUIDs changed, and gummiboot complaining etc etc For now I am tired and leave it like that for today (late here). Thanks, Stefan
