Ok, this is a problem with the 000-cygwin-post-install.sh script now:
if [ ! -e "${DEVDIR}" ]
then
mkdir -m 755 "${DEVDIR}"
if [ ! -e "${DEVDIR}" ]
then
echo
echo "Creating ${DEVDIR} directory failed."
echo "Please fix that manually, otherwise you WILL get problems."
echo
exit 1
fi
fi
The non-device files under /dev can only be created, if /dev exists
on disk.
However, if /dev does not exist as real directory on disk, it's handled
as virtual read-only filesystem to be able to list the device files even
then. Therefore the first
if [ ! -e "${DEVDIR}" ]
fails and the mkdir is never called. Consequentially subsequent calls
to create files and/or directories fail as well. So the above code has
to be changed like this:
mkdir -m 755 "${DEVDIR}" 2> /dev/null
if [ ! -e "${DEVDIR}" ]
then
echo
echo "Creating ${DEVDIR} directory failed."
echo "Please fix that manually, otherwise you WILL get problems."
echo
exit 1
fi
This works for me. Can you test this as well, please? I will fix the
base-cygwin package ASAP.
Thanks,
Corinna
