checkroot.sh uses the function to tell whether or not /dev/shm is writable.
mountvirtfs uses the function to tell whether or not /dev is writable.
These tests could probably be eliminated or implemented in a different way.
Current code in checkroot.sh:
if dir_writable /dev/shm ; then
rm -f /dev/shm/root
mknod /dev/shm/root
else
print error message
fi
Possible alternative:
if ! { rm -f /dev/shm/root && mknod /dev/shm/root ; } ; then
print error message
fi
Current code in mountvirtfs:
if dir_writable /dev && [ ! -c /dev/ptmx ] ; then
mknod /dev/ptmx
fi
Possible alternative:
if [ ! -c /dev/ptmx ] ; then
mknod /dev/ptmx || :
fi
