May I suggest first moving everyt= hing into /usr one at a time, and for each file moved out of /bin or /sbin = or whatever, replace it with a symlink?

This will allow the /b= in and /sbin directories themselves to atomically be replaced with symlinks= later.

Doing it all at once will leave a gap.

Fo= r each file:

1.=C2=A0 Install it in the new location
= 2.=C2=A0 Delete the old file and replace it with a symlink

 Considering the advantages of usr-merge are rather specific IMHO but risks = during the migration are high, I think you're optimistic on the user ba= se of usr-merged systems :)

Heck, it hasn't happened yet because there hasn't been such a big n= eed for it.
