Re: [Libguestfs] virt-resize

For now, UFS in Linux do not support resizing at all. There is only
one way to resize: create new image, partition, attach to existing
freebsd, install bootloader, sync files.

Don't think guestmount even supports ufs even if it is enabled either:
Did a quick download of this read only ufs module: rpm -i kmod-ufs-0.0-1.el6.elrepo.x86_64.rpm

cappy:~# modprobe ufs
cappy:~# guestmount -a /dev/virtual/freebsd -m /dev/sda2 /freebsd -r
libguestfs: error: mount_options: /dev/vda2 on /: mount: unknown filesystem type 'ufs'
guestmount: '/dev/sda2' could not be mounted.  Did you mean one of these?
        /dev/vda1 (unknown)
        /dev/vda2 (ufs)
        /dev/vda3 (unknown)
cappy:~# kpartx -av /dev/virtual/freebsd
add map virtual-freebsd1 (253:6): 0 128 linear /dev/virtual/freebsd 34
add map virtual-freebsd2 (253:7): 0 19920768 linear /dev/virtual/freebsd 162 add map virtual-freebsd3 (253:8): 0 1048576 linear /dev/virtual/freebsd 19920930 cappy:~# mount -t ufs -o ro,ufstype=ufs2 /dev/mapper/virtual-freebsd2 /freebsd
cappy:~# ls /freebsd/
bin boot COPYRIGHT dev entropy etc home lib libexec media mnt proc rescue root sbin sys tmp usr var

Guess still some uses for kpartx, curious what outcome would have been if a recompiled kernel with read-write ufs support here, or is ufs hardcoded
as non supported?

We can't currently resize BSD guests; patches welcome ...
