Hi all,
I have an encrypted file that was made on 4.7. Here are the steps I took.
1. Created around a 22G file zero'd out.
# dd if=/dev/zero of=/path/encrypted_file bs=512 count=109113984
2. Created a salt file.
# dd if=/dev/arandom of=/etc/salt/secure.salt count=1
3. Associated svnd1 with 'encrypted_file' (and entered my password).
# vnconfig -v -c -K 1440 -S /etc/salt/secure.salt svnd1 /path/encrypted_file
4. Partitioned and formatted the virtual device with one 'a' partition.
# fdisk -i svnd1
# disklabel -E svnd1
# newfs /dev/rsvnd1a
However, I'm having trouble opening the 'encrypted_file' on 4.8. Here's the
steps
I'm taking.
1. Associated svnd1 with 'encrypted_file' (and entered my password).
# vnconfig -v -c -K 1440 -S /etc/salt/secure.salt svnd1 /path/encrypted_file
The following is a comparison between 4.7 and 4.8 fdisk svnd1.

The partitions are un-aligned. And I'm unable to mount the 'a' partition
that
I made in 4.7.
Anyone have any ideas what the problem might be??
Thanks all for your time,
Mike
