I decided to bump my laptop up to 5.0-CURRENT today. All seems to have
gone well and all my old binaries work fine, it looks very nice.
However, I can no longer mount my linux partition: when I try, I get
# mount -t ext2fs /dev/ad0s2 /mnt
ext2fs: /dev/ad0s2: No such file or directory
Did something change when I install new bootblocks, and how do I fix it?
Below, output from fdisk and disklabel. I don't remember anything unusual
before the upgrade.
Thanks,
Rahul
