Hello :-)

I am new to journaled UFS2, so there goes some questions and remarks:

1. GJournal MUST be run before NewFS, especially on one provider, this
should be clearly stated in NewFS manual, before hotshots like me first
create the fs and then want the journal, please update.

2. Is it possible to automaticaly create journal by NewFS when -J flag is
set?

3. Is it possible to add journal to existing partition (partition and
journal are on the same provider) without loosing data on that partition?
Gjournal warns that running label -f will destroy the data...

4. When I want to use data and journal on one partiton partition.journal
appears after I create a label with gjournal. Why do I mount
partition.journal not the partition?? Isn't the journal something that
makes data partition to work aka backend? Isn't the journal a metadata that
keeps the record of files, if so why do I mount this metadata, this looks
odd.

5. In my 9.1-RC3 I see no .journal device for /partition - does it mean
that journal is not created by default?? Does bsdinstall remember to first
greate gjournal?

Any hints welcome :-)
