How to know what file systems are supported by the Linux kernel
How to find mountable devices and their device files in Linux?
How can I allow a regular user to mount a device in Linux?
Thank you very much

IIRC, only block devices are directly mountable, and they usually live in the /dev tree.
find /dev -type b
Your other two answers are in the mount man page
The non-superuser mounts.
Normally, only the superuser can mount filesystems. However, when fstab contains the user option on a line, anybody can mount the corresponding system.
Thus, given a line
/dev/cdrom /cd iso9660 ro,user,noauto,unhide
any user can mount the iso9660 filesystem found on his CDROM using the command
For more details, see fstab(5). Only the user that mounted a filesystem can unmount it again. If any user should be able to unmount, then use users instead of user in the fstab line. The owner option is similar to the user option, with the restriction that the user must be the owner of the special file. This may be useful e.g. for /dev/fd if a login script makes the console user owner of this device. The group option is similar, with the restriction that the user must be member of the group of the special file.-t, --types vfstype
The argument following the -t is used to indicate the filesystem type. The filesystem types which are currently supported include: adfs, affs, autofs, cifs, coda, coherent, cramfs, debugfs, devpts, efs, ext, ext2, ext3, ext4, hfs, hfsplus, hpfs, iso9660, jfs, minix, msdos, ncpfs, nfs, nfs4, ntfs, proc, qnx4, ramfs, reiserfs, romfs, squashfs, smbfs, sysv, tmpfs, ubifs, udf, ufs, umsdos, usbfs, vfat, xenix, xfs, xiafs. Note that coherent, sysv and xenix are equivalent and that xenix and coherent will be removed at some point in the future — use sysv instead. Since kernel version 2.1.21 the types ext and xiafs do not exist anymore. Earlier, usbfs was known as usbdevfs. Note, the real list of all supported filesystems depends on your kernel.

- I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.
where 'N' is the partition number, and 'mount-point' is the empty directory you created.Sometimes, real fast is almost as good as real time.
