fedora / mounting point
by Patrick Dupre 01 Mar '13

01 Mar '13

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?

mount --move in fedora 18
by Norman Gaywood 28 Feb '13

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? -- Norman Gaywood, Computer Systems Officer University of New England, Armidale, NSW 2351, Australia ngaywood(a)une.edu.au Phone: +61 (0)2 6773 2412 http://mcs.une.edu.au/~norm Fax: +61 (0)2 6773 3312 Please avoid sending me Word or Power Point attachments.
