It is not clearly documented, but apparently fsck
(or, probably, getmntent) is using backslash as
escape character.
Label containing slash is converted to \x2f but '\'
is eaten by fsck later. Escape '\' before writing
into fstab.
v2:
- fix sed expression
- use printf instead of echo because echo eats '\' as well

maybe we should just turn \x2f back into / ??
