As others have said, no. However, I keep wondering if an overlay file |
| 15 |
system might not be of some use here. Start with /bin, containing only |
| 16 |
what's necessary to boot before /usr is available. Once /usr is |
| 17 |
mounted, overlay mount /usr/bin on /bin (or would it be the other way |
| 18 |
around?) |
