Running `fim-mount` hangs forever when mount directory doesn't exit

When attempting to run fim-mount on the alpine image, I noticed that running ./alpine.fim fim-mount or ./alpine.fim fim-mount ./dir (where ./dir doesn't exist) causes the command to just hang forever with no output.

I'm assuming this is a bug, but I'm not positive.

I think this is a bug too, but I ran mkdir ./mount first (./mount is the directory I'm mounting at), and running fim-mount ./mount is showing this message:

/tmp/fim/instance/7de4257_20231001041443/boot: line 635:  3183 Segmentation fault      "$FIM_DIR_GLOBAL_BIN"/e2fsck -fy "$FIM_FILE_BINARY"\?offset="$FIM_OFFSET" &> "$FIM_STREAM"

It looks like the segfault in that last comment was just due to my image, redownloading a new copy of the alpine image removed the segfault.

The new image is showing this error about running touch on a file when using a non-existent directory though (and the original error is now gone):

touch: cannot touch '/tmp/fim/instance/7de4257_20231001041443/mount/dNcAol/fim/config': No such file or directory

And now I'm back to the hanging again, I'm not quite sure what triggered the above scenario :p.

Hi @hwittenborn , thanks for reporting this issue! That is pretty weird, I'll give it a shot, when the mounting is successful there currently is no output, it hangs so you can press CTRL+C to un-mount.
