I don't use an automounter. I like to be in control of what gets
mounted when. Thanks for the explanation. With it in mind I've finally
come up with a plan that works. In /etc/sudoers.d/001 I've included...
waltdnes i3 = (root) NOPASSWD: /sbin/fdisk -l /dev/sdc
And there's an entry for a vfat device in /etc/fstab for directory
/mnt/extc. The command "/sbin/fdisk -l /dev/sdc" seems to read in the
partition table into the system and things work from there on in. fdisk
only works as root, hence the sudo command. Here's a sample session...
===================================================================
waltdnes@i3 ~ $ mount /mnt/extc
mount: special device /dev/sdc1 does not exist
waltdnes@i3 ~ $ sudo /sbin/fdisk -l /dev/sdc
Disk /dev/sdc: 16.0 GB, 16012804096 bytes
256 heads, 63 sectors/track, 1939 cylinders, total 31275008 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Device Boot Start End Blocks Id System
/dev/sdc1 * 2048 31275007 15636480 c W95 FAT32 (LBA)
waltdnes@i3 ~ $ mount /mnt/extc
waltdnes@i3 ~ $
===================================================================
The mount after "sudo /sbin/fdisk -l /dev/sdc" is successful. So all
I need is a short script "~/bin/mntc" like so...
#!/bin/bash
sudo /sbin/fdisk -l /dev/sdc
mount /mnt/extc
