On the hppa platform the fstype program from klibc crashed (details in
Bug#745660) which exposed a problem in the
get_fstype() shell function in file scripts/functions.
In this script, fstype is called like this:
eval $(fstype "${FS}" 2> /dev/null)
if [ "$FSTYPE" = "unknown" ] ....
Since fstype crashed and returned nothing in the variable "FSTYPE", FSTYPE
stayed empty instead of the value "unknown" and as such no further analysis via
blkid was done.
I think it makes sense to pre-initialize FSTYPE to the value "unknown" before
calling fstype. That way the program logic will continue correctly if something
with the fstype program is wrong.
Attached script fixes this.
Please apply.
