Mageia
------
Mageia, both in its stable (6.1) and its development (cauldron)
versions, is still offering v3. This is due to a problem with
directories in cpool/ being created by v4 with world writeable
permissions (probably also in pc/, I can't verify at present), see
https://bugs.mageia.org/show_bug.cgi?id=24010
Since the parent BackupPC directory on the server should have 0 world
access permissions this is not dramatic. But there is also the issue
that v4 makes msec (Mageia security checking tool) output tons of
security warnings about world-writeable directories - and it is bad
security policy to accumulate backup data that has the flaw of
non-perfect write protection.
With the suggested patch, directory permissions do become OK and v4.0
runs smoothtly - but the patch is only a temporary workaround (made with
the intent to exlude the risk of introducing problems elsewhere). The
underlying problem is probably a umask issue.
Personally, after applying the patch, I am perfectly happy with v4 and
use a self-made correspondingly built package in production: full
satisfaction. Presently my server is configured to maintain the old v3
data along with the newly added v4 backup data. I have not yet decided
whether I will convert my backup data to all-v4.
Mageia is presently preparing a new stable release (Mageia-7, release
foreseen for something like April). The decision lies with the
development engineers whether they consider the patch sufficient for
having v4 in Mageia-7 or whether they expect a well thought-out
correction from upstream.
