Fedora 18 existing /usr partition -- need to merge into rootfs? - users - Fedora Mailing-Lists

Monday, 1 April 2013

Hey all.

I'm confused over the whole separate /usr partition is broken thing:
http://freedesktop.org/wiki/Software/systemd/separate-usr-is-broken

...
From an email in current fedora-user thread we have: "That
should not be necessary.  And would break a very normal system
setup of using separate drives, *even more so than the blasted can't have
a separate /usr thing that happened recently*."

During Fedora 18 fresh install with custom partitioning chosen, Anaconda
autocompletes mount points so I went with /boot, /, /user, /var, and /home
partitions.

Everything appears to work swimmingly here after 1 month of use -- separate
/usr partition does not appear to be broken...anymore??

Just trying to future proof my setup; if it's better to merge /usr into
rootfs, so be it, better to do it early days with the new system.

Otherwise, if someone can chime in here with some sage partitioning advice
as to how to proceed moving forward with Fedora, that would be much
appreciated.

FWIW, as a beginner the benefits I see in a diverse micro-managed
partitioning scheme (vs. the mega partition) is being able to fsck quickly;
clone partitions quickly (e.g. copy to additional disks), and prevent
runaway logs and the like (there are likely others).

I'm thinking something like this would be "ideal" for a 256GB SSD:

/dev/sda1 /boot 181MB of 500MB
/dev/sda2 / 606MB of 3GB

extended:
/dev/sda4 /usr 6.0GB of 12GB
/dev/sda5 /var 1.5GB of 8GB
/dev/sda6 /home 15GB of 30GB
free space the rest

Of course most seem to go with /boot / and /home, so my ideas are likely
not grounded in reality ;-)

 Subject: Using Exim as a controlled relayer
 I've managed to get the Exim + Pgsql setup working.

 For the domains I'm hosting I have a set of records which contain an email
 address within the domain and an delivery email address, e.g.

 user(a)hosted.domain ->           gary.stainburn(a)ringways.co.uk

 When I test this using

 exim -bt user(a)hosted.domain

 it works fine, but when I try to send an email it fails

 relay not permitted.

 Obviously i do not want to turn on relaying, so how can I configure Exim to
 allow emails that have matched a record in the user table to be forwarded?

 "noauto" is your friend and the last bit to zero which indicates at least
 "no fsck"
 never configure temporary drives as like built-in ones

 [root@localhost:~]$ cat /etc/fstab  | grep noauto

 you could add the following to /etc/yum.conf

 You mean like the one in my set-top box?

 package-cleanup can also be useful in this context.

 Subject: Fedora 18 network printer setup
 I have a Brother DCP-7065dn printer scanner connected to my LAN.

 Sadly, it requires a proprietary driver.  I've installed that.
 <http://welcome.solutions.brother.com/bsc/public_s/id/linux/en/index.html>

 I asked the System Settings: Printers to set it up (add the printer).
 The SS:P found the printer (so it must have found its IP address) and
 added it.  But the SS:P was only willing to configure it with the IP
 Address "localhost".  Not surprisingly, printing didn't work.

 I even tried telling SS:P the printer's IP address, but it ignored
 that and used localhost.

 I used SS:P to remove the printer again.

 I used the CUPS web server to add the printer (as suggested on the
 Brother page).  That worked.  My printer has a static IP address,
 which made pointing Firefox at it easier.

 Why would Systems Settings: Printers not be able to add this network
 printer?

 That should not be necessary.  And would break a very normal system
 setup of using separate drives, even more so than the blasted can't have
 a separate /usr thing that happened recently.

 I've used separate home drives, in the past, as a very simple way of
 being able to safely update a server without any chance of screwing up
 user data.  Others have used separate swap drives as a way of speeding
 up swap, should you ever be stuck with having to make use of it.  It's
 bad enough to have to use a drive for swap space, without having to put
 up with the thrashing of alternating between swapping and everything
 else it's trying to access on the drive.

 Anyway, I note the original poster says they've solved their problem.

 It strikes me that the "snoopy" services will probably have no trouble
 reading something as un-bizarre as ext4.  I dare say that such things
 are child's play to them.  It would be a tech that would assess
 hardware, not just any member of their staff.

 I would, also, think carefully about whether you really do need the
 force flag.  Some people just jam that in out of habit.

 Bearing in mind your bowlderised example, my simplistic answer would be
 to use real domain names (that you own) in your network.  Things work a
 lot easier when you don't use fake domain names.  Being able to email
 between machines, for just one example.

 That's odd.  What output does this command give?:

 su -c 'lpinfo -l -v'

 (I'm hoping it lists the network printer there...)
