I have a system that used to have 3 different Linux flavours running. I no longer wanted one of them so I moved and expanded with gparted and all is well, except I now have /sda3, /sda4, /sda7, /sda8 - I deleted /sda5 and /sda6 - so I have a gap in the sequence.
I've seen that gdisk offers a 'sort' function, which looks like it might work. I can perform the sort operation, and print results and I end up with a nicely sequenced bunch of GPT partitions. I am yet to be bold enough to (w)rite the changes to disk.
My concern is that I'll need to edit /etc/fstab and / or /boot/grub/grub.cfg following this, or can I simply update-grub, to fix any config file issues?
Can anyone advise?
