Re: vital packages

Hi,

Currently, FreeBSD’s pkg installs software by uninstalling the old
package before installing the new one. This approach has broken my
system, because the new package failed to install while the old one
had already been removed.

I believe it would be safer if pkg could automatically create a
snapshot of the last bootable system using ZFS or UFS before making
such changes.
