Should the swap partition(s) be installed at the start or the
end of the (ssd) disk? Or does it matter? The filesystem is ufs.
The partition table looks like this right now
# gpart show da0
=> 63 1953525105 da0 MBR (932G)
63 1985 - free - (993K)
2048 102400 1 fat32lba [active] (50M)
104448 1953420720 2 freebsd (931G)
# cat /etc/fstab
# Custom /etc/fstab for FreeBSD embedded images
/dev/ufs/rootfs / ufs rw,noatime 1 1
/dev/msdosfs/EFI /boot/efi msdosfs rw,noatime 0 0
tmpfs /tmp tmpfs rw,mode=1777 0 0
/dev/label/growfs_swap none swap sw 0 0
md none swap sw,late,file=/usr/swap0 0 0
I plan on saving the disk image onto another machine first, re-partitioning the ssd
then copying back the freebsd part of the image. The purpose is to eliminate growfs_swap
and the md based swap. I'm thinking partition-based swap will be quicker even on ssd.
Is this correct?
