fedora / mounting point
by Patrick Dupre
Hello,
In Fedora 18 I am trying to install the / (root partition) on my
own partition, but it seems impossible?
Am correct?
"You must create a new filesystem on the root device"
Can I change later?
Thank.

mount --move in fedora 18
by Norman Gaywood
When using fedora and ltspfs, ltsp clients want to fuse mount their USB
drives onto the system into the /media directory. This mostly works except
for the last step of move mounting into the /media.
The part that fails is the equivalent of the last line in these steps:
mkdir -p /tmp/testing
cd /tmp/testing/
mkdir -p foo bar
mount -t tmpfs tmpfs foo/
mount --move foo bar/
The last step will give the error:
mount: wrong fs type, bad option, bad superblock on /tmp/testing/foo,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
This worked (the mount --move) in Fedora 16 (without sandbox installed) and
Fedora 17. But not in fedora 18.
When the bug appeared briefly in F16, this bug:
https://bugzilla.redhat.com/show_bug.cgi?id=838447
was logged. As noted there removing sandbox fixed the problem.
F18 seems to make use of pam_sandbox which is probably want is stopping the
mount --move this time.
So how do I configure/remove pam_sandbox so the mounts will work again?

Finally I solved this problem by just changing permission on server
directory.
server# chmod o+x /borneo4
Now my client can access without any problem.

NFS Client: Backup preparation problem
by Amit Karpe
Hi All,
I am not able to access particular directory on client which is mounted
using NFS.
client# ls -l /mnt/tmp
ls: cannot access /mnt/tmp/del: Permission denied
total 0
?????????? ? ? ? ? ? del
I have following disk on server.
server# ls -ld /disk12
drwxrwxr-- 3 root root 4096 2013-02-28 15:53 /disk12
Entry in /etc/exports on server.
/disk12 172.21.123.219(rw,sync)
On client
Entry in /etc/fstab
172.21.123.225:/disk12 /mnt/tmp nfs
fsc,rsize=32768,wsize=40960,rw 0 0
If I used no_root_squash in /etc/exports on server I can access directory
without problem.
/disk12 172.21.123.219(rw,sync,no_root_squash)
What can be the problem ?
