Error: Invalid cross-device link

[Rahul Nabar]

I get an error when I try to issue a command:

bzr revert /var/www/html/euclid_logs.html
bzr: ERROR: [Errno 18] Invalid cross-device link

bzr log /var/www/html/euclid_logs.html

Other bzr commands do work fine.

/var is indeed mounted on a different physical device but that's all
right I guess?

/dev/sda6             95283436    979016  89386124   2% /var
/dev/sda5             14877060    169792  13939364   2% /tmp

I started out by doing:
cd /
echo '*' >>.bzrignore
bzr init /
 bzr add .bzrignore
 bzr commit -m "Ignoring everything" .bzrignore

Any tips what I could be doing wrong?
