I'll have to join the chorus of objections here. That tool doesn't seem
to be available anyplace on the kmenu. If thats the 'approved' tool to
do that, then it needs to be a heck of a lot more accessible than buried
someplace in an sbin directory that you have to issue a 'locate
system-config' and see what falls out with a name that *might* indicate
it what you want.

Fedora has taken perfectly good code, and broke it all to hell making it
fit in the rpm format, on several occasions. Often the packager doesn't
use it himself, and has no idea how to go about throwing it out in the
street to see if it can survive in traffic. Sorry if thats a bit too
candid an opinion, but back when I wanted to start using it, I screwed
around with whatever version was in rpm at the time for almost 3 months
fighting with perms, finally discovering the mailing list, and got
instructions on how to build it. The result worked the first night. And
every night since except for an obscure bug that effected several
snapshots in a row last spring, and a typo in the srcs of two snapshots,
probably 5 & 2 years ago. Stable? Yes, very. We have 10x the trouble
with gnu.org's ongoing screwing with tar, to the extent we now have a
list of tars that work and tars that will not recover. In that regard,
amanda is many times more stable that tar. But you folks always think
tar is stable, so you go get the last release, make an rpm out of it, and
apparently never actually test it in the real world. We do. Every
night...
>From time to time one of the packagers checks into the list, and tries to
understand the problems. But then like smoke in a whirlwind, gone again
for 2 years or more because we think this is a great time to get amanda
fixed, but your packager has thin skin & boogies. To get an idea of what
it can do today, go get the latest snapshot from Jean-Louis's site at
umontreal, link near bottom of page at amanda.org, unpack it, and read
the ChangeLog. I don't even know if it goes back as far as the version
fedora is currently shipping, but a lot of new capabilities have been
added since then, with the only backwards breakage being the timestamps
which once enabled in the wider format aren't compatible with
pre-timestamped archives that have only a date stamp.

Valid for the FC2 tree's, amanda is 501 on FC6. I probably am overdoing
it, but I (root) just 'chown -R amanda:disk *' from inside
the /home/amanda dir.
Point taken though. Thanks.
