y> MS-DOS had a read-only attribute, with no concept of users. Even though the
read-only attribute could be turned off, it was still useful, for preventing
modification or deletion by "normal" code which didn't go to the trouble of
turning it off.
From the DOS world it has a read only bit. But from the POSIX world,
which eCos follows, that has to be mapped into owner, group and other
read, write, execute bits. Its the POSIX in the middle that makes it
complicated. Also you have problems with ".. trouble of turning it
off." Like i said, there is no chmod() so you cannot enable writing
from eCos.
