On Linux 2.6.39-rc1+, mountinfo occassionally shows an extra UUID field, but does not show a "-" for when the uuid is absent. This could be a kernel bug. It this throws off util-linux v2.19-136-g2ac1890 parsing at some point: # mkfs.ext4 /dev/ram0 # mount /dev/ram0 /mnt # column -t /proc/self/mountinfo 40 18 0:36 / /home rw,relatime - nfs4 10.10.1.1:/home/ rw,vers=4,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=10.10.1.212,minorversion=0,local_lock=none,addr=10.10.1.1 41 18 0:34 / /var/lib/nfs/rpc_pipefs rw,relatime - rpc_pipefs rpc_pipefs rw 43 18 0:3 / /var/lib/ntp/proc ro,nosuid,nodev,relatime - proc proc rw 44 18 1:0 / /mnt rw,relatime uuid:4b0a7863-73a4-4722-be7b-3a29ada68c4d - ext4 /dev/ram0 rw,user_xattr,acl,barrier=1,data=ordered # ./shlibs/mount/samples/mount shows: - on /mnt type 73a4-4722-be7b-3a29ada68c4d (rw,relatime,ext4) -- To unsubscribe from this list: send the line "unsubscribe util-linux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
