[Toaster] FW: request for review

Hi Alex,
See comments inline which cover 2 topics
1) should we keep permissions as a string, since views will always display strings
2) what about the other inode types: 'c', 'b', 'p', 's'

What about the other types of inodes?  Which of the following can't be in an image:
devices (character, block), fifo's, sockets?

I'm doing the opposite translation, so this seems wrong and we should keep a string.
Also, my perms translation handles links s[-1] = 'l', sticky /setuid/setguid permissions.  Maybe it would be better to keep this a string.

See comment above, maybe better to treat like 'user' and 'group' just leave it a string.

This deals with my concern about other inode types and if they can actually be represented in installed_img_path,  fifos (pipes), sockets, block and character devices, as discussed above and in last comment below.

Other possibilities may be startswith("c", "b", "p")?  Can you check with someone who knows for sure that these can be stashed and saved in an image?
