Bug 274223

Created attachment 245389 [details]
Error message when /mnt fills up.

The v14.0 installer has a broken version of the /usr/libexec/bsdinstall/scriptedpart utility. It partitions the target disk properly, but doesn't write the target disk layout to an fstab file, as it should. Because of this, the '
'bsdinstall mount' step fails to mount the target disk onto the /mnt mountpoint. Because the /mnt directory is setup as a tmpfs (with my configs), the installer continues. It then either a) fails when the /mnt partition runs out of space, or b) if the tmpfs is large enough, completes the install, only to have it disappear when the VM reboots.

This issue was discovered with HBSD v14.0 and then confirmed using the FBSD 14.0 BETA4 and BETA1 installers. See these emails for more verbosity on the subject.

I've confirmed this bug on QEMU using the AMD64. The other hypervisor installs (Vbox, Vmware, Hyper-V, etc) also failed, so I assume the bug isn't platform specific, but I haven't pulled up the console on the systems to confirm.
