RFC: [2.6 patch] remove UMSDOS

From: Adrian Bunk
Date: Sun Jul 11 2004 - 06:30:47 EST

UMSDOS in 2.6 is broken, and it seems noone needs it enough to bother
fixing it.

I'd suggest the patch below to remove UMSDOS.

- Say Y here if you want to run Linux from within an existing DOS
- partition of your hard drive. The advantage of this is that you can
- get away without repartitioning your hard drive (which often implies
- backing everything up and restoring afterwards) and hence you're
- able to quickly try out Linux or show it to your friends; the
- disadvantage is that Linux becomes susceptible to DOS viruses and
- that UMSDOS is somewhat slower than ext2fs. Another use of UMSDOS
- is to write files with long unix filenames to MSDOS floppies; it
- also allows Unix-style soft-links and owner/permissions of files on
- MSDOS floppies. You will need a program called umssync in order to
- make use of UMSDOS; read
- <file:Documentation/filesystems/umsdos.txt>.

- This option enlarges your kernel by about 28 KB and it only works if
- you said Y to both "DOS FAT fs support" and "MSDOS fs support"

- called umsdos. Note that the file system of your root partition
- (the one containing the directory /) cannot be a module, so saying M
- could be dangerous. If unsure, say N.
