yep, i got this too. fix is trivial, we're just missing a backslash in

I was setting up a diskless client, using dhcpd to get info then booting pxeboot then a kernel created for DISKLESS per a combination of instructions in the handbook and Luigi's notes in the /usr/share/examples/clone_root script. The client gets an /etc/rc.diskless which fails to mount volumes such as /var, which it's supposed to create and mount as a "memory disk". It's supposed to default to 4MB but this fails, and it's supposed to be overridden by a "md_size" file in the template partition, but that failst the same way. I don't see anywhere in the script where it $md_size_$1 is set before invoking create_md() but the logic is comparing "$md_size_$1" = "x" and thus erroneously compares "var" with "x" and thus doesn't get the default. Fix: I have a gross work-around that just jams a value into md_size before doing the mount, but this isn't really a fix. create_md() { echo "RC.DISKLESS1 CREATE_MD='$1' size='$md_size_$1'" if [ "x`eval echo \\$md_created_$1`" = "x" ]; then if [ "x`eval echo \$md_size_$1`" = "x" ]; then md_size=8192 else md_size=`eval echo \\$md_size_$1` fi -> # Force the size since we can't get it reliably!! -> md_size=8192 mount_md $md_size /$1 /bin/chmod 755 /$1 eval md_created_$1=created fi } How-To-Repeat: execute $ROOT/etc/rc.diskless1 and see complaint: mount_mfs: /etc: bad file system size
