i have just installed the feb 20 snapshot on a personal netbook (not server). to install snapshots, i normally download the iso, copy the files from it to my home, and boot up bsd.rd and then select the sets from an "already mounted" partition.
i feel the latest incarnation of the installer is a bit hysterical about the checksum verification and i had to enter "yes" 12x, for every single set. this is quite annoying and perhaps it could be reverted back to the previous method where a single "yes" was enough to convince the installer that i am ok with non-verified sets. -f -- that'll be all for now, other than to say "hi" to Wonko if he's watching.
