Mark,

I just got a problem report about wiper.sh needing /usr/sbin/rdev.

If you need to depend on it, maybe you need to add the above logic to hdparm (or create a small standalone utility inside your package)?

Thanks.

How does this look to you for a bash rdev equivalent:

   ## Try and determine the device name associated with the root filesystem.    ## This is nearly impossible to do in any perfect fashion.    ##    ## do_rdev *usually* works, but on some distros it may only find "/dev/root",    ## and "/dev/root" is not usually a real device.  We leave it like that for now,    ## because that's the pattern such systems also use in /proc/mounts.    ## Later, at time of use, we'll try harder to find the real rootdev.    ##    ## Redhat/Fedora no longer have an rdev command.  Silly them.    ## So we now implement it internally, below.    ##    STAT=/usr/bin/stat    FIND=/usr/bin/find    function match_rdev() {            rdev=""            rdevno="$1"            while read bdev ; do                    if [ "$rdev" = "" -o "$bdev" != "/dev/root" ]; then                            devno=$($STAT -c "0x%t%02T" "$bdev")                            [ "$devno" = "$rdevno" ] && rdev="$bdev"                    fi            done            echo -n "$rdev"    }    rootdev=$($FIND /dev/ -type b 2>/dev/null | match_rdev $($STAT -c "0x%D" '/'))    [ $verbose -gt 0 ] && echo "rootdev=$rootdev"

That's what I'm intending to replace rdev with in wiper.sh v3.3. But I don't have any installs here that use "/dev/root" to re-test with. Gotta hunt around some more, I guess..

Mark, I'm not familiar with /dev/root. On my opensuse 11.3 machine, its a symlink to /dev/sda5. I ran your script and it echos "rootdev=/dev/sda5". My fstab has: LABEL=root / ext3 acl,relatime,user_xattr 1 1 I could change that to have /dev/root in the first column and reboot if you think it a useful test for you, but I suspect you need something booting from a LVM setup for /dev/root to be a meaningful problem?
