--- Begin Message ---Package: parted Version: 2.3-9.1 Severity: normal As a non-privileged user, i have r/w access to a specific block device (created by the device mapper). But when i try to use parted to interrogate or change the device, i get an error after the expected "Watch out for permissions" warning. This failure seems inappropriate, since i ought to be able to use parted in this context to inspect modify the contents of the the block device even if i can't talk to the device mapper directly. Feel free to forward this further upstream if that would be useful. Below is a transcript showing the problem: 0 dkg@pip:~/tmp$ ls -l $(readlink -f /dev/mapper/vg_pip0-test) brw-rw---T 1 dkg disk 253, 7 May 2 22:59 /dev/dm-7 0 dkg@pip:~/tmp$ [ -r /dev/dm-7 ] 0 dkg@pip:~/tmp$ [ -w /dev/dm-7 ] 0 dkg@pip:~/tmp$ /sbin/parted /dev/dm-7 print WARNING: You are not superuser.
