I'm a newer user to Arch and Linux in general. I've got a pretty robust installation running on my computer with Fluxbox, PCManFM and SLiM for the graphical side (if these matter). Everything's running pretty well at the moment except I'd like to be able to auto-mount USB storage devices. Without adding the udev rule as mentioned here (because I would like the mounting to persist through a terminal window popping open), what's the best way to have things auto-mount like they do in Ubuntu or Windows? By this I mean I would plug in a USB flash drive and it'd automatically be mounted to somewhere like /media/<device name>/ and any user (or the one running x? or something) would have permissions to view/edit/execute.

@ckielstra Since there is no other suggestions I have 2 thing you could look at. /etc/config/fstab allows you to set up mount points with the various configs. I use one for the sdcard on my devices to set up the mount point and the file system type. The docs refer to an additional "options" option which can be used to set mount options. I expect this includes the ro option but I have not tried it. The USB hotplug script is executed when you insert a USB device, you could add your own script to remount in read only mode. This is a hack you could use in the absence of a better solution.

@Lino-Amorim I think these are useful commands: ls -l /dev/sd* mount without parameters or mount | grep /dev/sda1 df -hT or df -hT | grep /dev/sda1 ls -lA /mnt, ls -lA /mnt/sda1, ... Some "technical" info: fdisk -l lsusb -v If you want to use the lsusb command: enable the second (2nd) line in the '/etc/opkg//distfeeds.conf' file and opkg update opkg install usbutils For example: Omega2+ FW v0.3.2 b232 with 8GB MicroSD card and 8GB FAT32 formatted USB pen drive with Expansion Dock This is a "fake" Omega2 Pro - using FW omega2pro-v0.3.2-b232.bin root@Omega-99A5:/# ls -l /dev/sd* brw------- 1 root root 8, 0 Jan 1 1970 /dev/sda brw------- 1 root root 8, 1 Jan 1 1970 /dev/sda1 root@Omega-99A5:/# mount | grep /dev/sda1 /dev/sda1 on /mnt/sda1 type vfat (rw,relatime,fmask=0000,dmask=0000,allow_utime=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro) root@Omega-99A5:/# df -hT | grep /dev/sda1 /dev/sda1 vfat 3.7G 388.9M 3.3G 10% /mnt/sda1 root@Omega-99A5:/# ls -lA /mnt drwxr-xr-x 5 root root 0 Jan 1 1970 mtdblock6 drwxrwxrwx 4 root root 4096 Nov 17 09:06 sda1 root@Omega-99A5:/# ls -lA /mnt/sda1 drwxrwxrwx 2 root root 4096 Oct 20 16:30 System Volume Information drwxrwxrwx 3 root root 4096 Nov 17 09:06 downloads -rwxrwxrwx 1 root root 402653184 Oct 20 15:19 swap.page root@Omega-99A5:/# ls -lA /mnt/sda1/downloads drwxrwxrwx 3 root root 4096 Nov 17 17:50 incomplete ### root@Omega-99A5:/# fdisk -l Disk /dev/mtdblock0: 192 KiB, 196608 bytes, 384 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 /dev/mtdblock1: 64 KiB, 65536 bytes, 128 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 /dev/mtdblock2: 64 KiB, 65536 bytes, 128 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 /dev/mtdblock3: 15.7 MiB, 16449536 bytes, 32128 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 /dev/mtdblock4: 1.5 MiB, 1572352 bytes, 3071 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 /dev/mtdblock5: 14.2 MiB, 14876672 bytes, 29056 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 /dev/mtdblock6: 6.6 MiB, 6881280 bytes, 13440 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 /dev/mmcblk0: 7.3 GiB, 7861174272 bytes, 15353856 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 Disklabel type: dos Disk identifier: 0x15d70756 Device Boot Start End Sectors Size Id Type /dev/mmcblk0p1 8192 15353855 15345664 7.3G b W95 FAT32 Disk /dev/sda: 3.8 GiB, 4007657472 bytes, 7827456 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 Disklabel type: dos Disk identifier: 0x04030201 Device Boot Start End Sectors Size Id Type /dev/sda1 1080 7827455 7826376 3.7G c W95 FAT32 (LBA) ### root@Omega-99A5:/# lsusb Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 002: ID 0951:1625 Kingston Technology DataTraveler 101 II Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub root@Omega-99A5:/# lsusb -v ...

I think I found the problem. The dmesg output showed superblock has an invalid journal. Repaired with fsck.ext4 /dev/sda2. Due to the size, it talks a really long time to complete all passes.
