Umsdos has some use even for Ext2 (Native Linux file-system) users. One common scenario is this:
Umsdos may save the day here. You can setup a Linux
directory in the DOS partition and use it without restriction
for Linux usage. For example, say you want to setup a new
directory named "extra"
in your C:
drive. And you want this
directory to behave as a normal Linux directory. Do this
(assuming that C: is /dev/hda1).
mkdir /c
/sbin/mount -t umsdos /dev/hda1 /c
mkdir /c/extra
umssync /c/extra
You must be root to do this.
By setting up /etc/fstab
like this, you will always
have access to the /c/extra
directory.
