Ubuntu 7.10 "gutsy" caveat: beware EVMS!
A small PSA: If you are upgrading Ubuntu to 7.10 “gutsy”, check to see if you have the “evms” package installed. If you do, and you have no knowledge of installing it and don’t know what it is, then you probably should remove it. The consequences of keeping it are a spew of system messages:
device-mapper: dm-linear: Device lookup failed
device-mapper: error adding target to table
Even worse, you may be unable to mount any partitions aside from /
! That’s what happened to me. 🙁
